29 Jan 2019
- As we appear to have a backlog on the Ultra, we ask the users to please
be respectful of the calendar. Removing the reservation less than 24
hours will not help other users to use the released time slots.
Please do not reserve the machine unless the sample is actually ready.
Users who have repeatedly disregard the booking rule will be suspended
indefinitely. Thank you for your cooperation.
15 Jan 2019
- New beginning
- By late summer 2019, WATLab would have provided materials analysis
independently for almost two decades ago at Waterloo. We have been
fortunate to have opportunities to set up one of the best toolsets for
advanced materials research in the world. Despite the various things
going on in 2018, WATLab will continue to serve our loyal users for as
long as we could. At the science/technology level, we are always
curious about the work of our users and how the present toolset can be
used to advance the goal of our users, i.e. from better data to better
publications. Please contact Nina, Lei and Joseph for more info.
Starting in Feb 2019, we will begin streamlining operation of the
quanta FEG in our continued effort to reduce cost. We ask our quanta
users to plan a bit ahead in booking time on the machine.
We take this
opportunity to wish everyone a Happy New Year and great data mining to
17 Dec 2018
- Happy New Year
- As we survive a difficult 2018, we look forward to a better
year to come. We thank our users for their continued kind support of
WATLab and we wish our users a happy and safe holiday and best of luck and
success in the Year of the Pig.
6 Dec 2018
- Quanta FEG second new source installed - resuming normal operation
- The second new source has been installed last week and the
Quanta appears to perform normally. Please reserve the system using
the appropriate google calendar. Happy data mining.
21 Nov 2018
- Quanta FEG off line
- Unfortunately, the new source installed a couple of weeks ago did
not last long. SFR has requested a new source to be shipped
immediately and will install it as soon as possible, likely by mid next
week. We thank our users for their understanding and patience.
14 Nov 2018
- LEO FEG down
- The electron source in
the LEO SEM has been experiencing a lot of
problems lately. LEO users should contact Nina for alternate SEM
services. Both the Ultra and Quanta are working OK.
8 Nov 2018
- Quanta FEG service is complete - Resuming normal
- This service has replaced the 3 years old FE source and a high voltage
cable-connector assembly. We will need to find some cash to
eventually replace the five Pt apertures (which will become dirty with
use). The images are excellent now. Happy data mining.
has created a big dent in our budget ($60k). Depending on the current
usage of the Quanta, we could conserve filament life (and reduce operating
cost) by running the tool every other week (except for emergency
situation). We will start this operating mode after Christmas.
We ask the user to please plan a little bit ahead and watch the booking
1 Nov 2018
- Quanta FEG service in progress
- The service engineer is on site this week and has started working on
replacing the FE source. More update later.
18 Oct 2018
- Quanta FEG down for source replacement
- After running for over 3 years, the FE filament in the Quanta has died.
All quanta users should contact Nina or Lei for alternative solution.
We are in the process of getting service to see if we could replace this
26 Jan 2018 - New
This year, we will be trying to bring the Raith Ion Beam Lithography
system on line and into user service. The Ion Beam Lithography
system is one of the very few such systems in the world, and it adds
unique capabilities not found in conventional lithography tools (such as
EBL). Currently, the source of this unique system is somewhat
unstable and the manufacturer is trying hard to stabilize operation.
The LEO appears to be stable at 20 kV and some users have begun to use the
Nabity EBL system again. We encourage users with high outgassing
samples to try out the Environmental SEM, with a very easy-to-use EDS
system. We are also accepting samples for TEM and FIB runs. We
are looking forward to an exciting year and wish the users best of luck
with their work in the coming months!
15 Dec 2017 - Merry
Christmas and Happy New Year!
- As WATLab must transition to a totally self-sufficient operating model
in an increasingly challenging environment in the next two years, we are
grateful to have the support of our loyal users. In the past several
months, some of the our machines have clearly shown their age and
experienced unforeseen downtime intermittently. We thank our users
for their patience and their understanding while we struggle to fix these
systems without a service contract. The University will close by Dec
22, and we take this opportunity to wish our users the merriest holiday
season, the best of luck in their research endeavour, and prosperous data
mining to come in 2018!
10 Nov 2017 - LEO
resuming user service
- We are bringing the LEO
back online and into user service. The probe current is lower than
spec but it is extremely stable (with variation less than 5%). The
image quality is also good. Please limit the EHT to not greater than 15 kV
(as anything higher than 15 kV could cause arcing and kill the gun).
As we will be resetting the user data base, please see Nina or Lei if you
experience any problem logging on. We thank you for your cooperation and
for your patience during the past several difficult months as we tried to
fix this SEM.
30 Oct 2017 - Removing
users not showing up
- As the Ultra is becoming rather busy lately, we wish to remind all users
to show up at the reserved time. Please remove your booking at least
24 hours before the reserved time (if your sample is not ready), so as to
allow other users enough time to rebook the released time. Please be
considerate to your fellow users, whose works are just as important and as
urgent as yours. We have begun to remove access privilege from users
whom we have not been able to convince to adhere to the reserved booking.
We thank you for your cooperation.
26 Oct 2017 - LEO
returning to user service, maybe?
The LEO suffered a filament loss in July - this was the shortest filament
lifetime that this machine has experienced, about 5 months. The
cause appeared to be a very tiny leak just above the column valve (V3).
Various attempts have been made to fix this leak. To minimize the
effect of this tiny leak on the filament, we have also rebuilt the ion
pump in the gun chamber to try to increase local pumping in this region
(which has caused a substantial delay). A new filament was activated
on Tuesday, and we are currently running some stability tests. If
the source is stable, we will release the machine for user service
hopefully by Nov 2. We thank our loyal users for their patience
during this challenging time.
7 July 2017 - LEO down for
the next four weeks - Other SEMs available
During the filament change of the LEO in June, we have encountered a
tricky vacuum problem in the gun. The engineer returned this week
but the problem remained unresolved. We will need to acquire some
more parts before we could go further. This unfortunately will take
some time (4-8 weeks). In the meantime, all SEM users are encouraged
to contact Nina re use of the Ultra (ultrahigh resolution SEM) or
Quanta (Environmental SEM), as appropriate. Some users will require
additional training (from Nina for the Ultra, and from Lei for the Quanta).
For the EBL users who depend on the LEO Nabity EBL system, we are
releasing the Merlin (state-of-the-art SEM) with advanced Fibics NPVE
nanofabrication tool. Lei is in the final stage of making the
workflow more robust. Please contact him for training. We
apologise for any inconvenience and we hope the current EM solution will
help to advance the research of our loyal users.
31 May 2017 - Charge
compensation in ESCALab
The Thermo engineer has resolved the charge compensation problem in the
ESCALab. The system is now close to spec and capable of handling
insulating samples. Highly outgassing samples (containing S and/or P)
remain a challenge for XPS facilities and UHV systems in general., because
S will corrode the lens elements over time, rendering the electron optics
ineffective. With the assistance of a few user groups, we
are developing a few pre-analysis sample cleaning protocols to see if we can at least reduce
this type of contamination issues.
31 May 2017 - High kV problem in LEO
The engineer is scheduled to be on site by mid June to see if we can
resolve the high kV arcing problem. Please hang tight. In the
meantime, we encourage the users to try out the ESEM and/or the Ultra.
21 Feb 2017 - Calendar
booking becoming unreliable
We have noticed that an increasing number of users signed up the tool but
failed to show up. This is unacceptable, because the no-show booking
is blocking another user from using the machine. Some deleted their
bookings a few hours or a few minutes before the reserved time slots and
hoped that no one noticed. Well, we do notice, and we are keeping
track of who is doing this. Those who continue to disregard the
honour system will soon lose their machine privilege.
the WATLab FAQ regarding
booking cancellation policy.
If you are not
sure whether your samples will be ready at the time of your booking, we
suggest that you do not book ahead. Instead, you should try a
"walk-in", i.e. check if the machine is free at the time you wish to use
the tool and if it's free, then you can just go ahead and use it until the
next reserved time. If you make a reservation on the calendar, we
and all other users expect you to show up.
Feb 2017 - LEO resuming normal operation - Ultra resuming
The FE source in the LEO has been replaced and the system appears to be
functioning close to spec. There is a minor change to the setup.
The EDS system still needs some calibration (use at your own risk) but the
SEM imaging is good.
Please see one of WATLab staff before startup.
For the Ultra, the on-going instability problem has been narrowed down to
the mechanical joystick. We have engaged the "soft joystick" to move
the stage. Please see one of WATLab staff before startup.
Ultra has also been upgraded to Windows7 and the latest version of
SmartSEM (V 6.0). Please report any issues to Nina or Lei.
24 Jan 2017 - LEO system down
After 2.9 year, the FE source in the LEO is finally gone. We have
contacted the engineer and help is on its way. Hopefully, we can get
this back up as soon as possible. Please watch this space for
further news. In the meantime, please see if your work can take
advantage of the environmental SEM.
Jan 2017 - Happy New Year !
WATLab remains Canada's premier advanced materials research lab that
supports multi-mission research with state-of-the-art and unique tools.
WATLab will try to survive better this year under an increasingly hostile
local operating climate. We don't expect significant changes to our
toolset this year, except to bring the new Raith IonLine system online and
into user service. This is Canada's first and only ion beam
lithography system (one of just a handful in the world) and we hope to
enable new device sciences with this new tool. We will also try to
resolve ongoing stability issues with the Ultra and to complete system
upgrades for the ESCAlab.
We thank our loyal users for their continued support, and we wish them a
fantastic year of discovery and lots of great data to come!
Dec 2016 - ESCA and Microlab upgrades in progress
The engineer is on site to upgrade the data systems for both the ESCALab
and MicroLab to W7. As with all upgrades and maintenance, there is
always a risk. These systems will be unavailable until further
notice. - Please contact Jung Soo or Lei.
Dec 2016 - Ultra PC upgraded with new SmartSEM
- The Ultra PC has been upgraded and we now have the latest version of
SmartSEM installed - all in preparation for commissioning correlative
microscopy. We are in the process of reestablishing all the SEM user
accounts - Please contact Nina.
Nov 2016 - Quanta FEG environmental SEM fully operational -
The FEI Quanta FEG has been on line and fully operational for nearly a
year. This system has full SSD EDS system and the image quality is
excellent because of the FE source. We encourage all the users with
highly outgassing materials (such as porous materials or loose powders) to
get trained on this machine - Please contact Lei or Nina.
Nov 2016 - New Correlative Light - Electron Microscopy coming to the Ultra
The new correlative light microscopy system along with the
unique Shuttle&Find system has been delivered and is expected to be
installed in 2-3 weeks. This upgrade will allow us to
correlate polarization and fluorescence LM info with detailed EM info.
May 2016 - New SSD-based EDS system coming to the LEO
- An Oxford Xmax SSD EDS system is on order and will replace our 15 years
old EDAX system. We expect to commission this as soon as possible
within the next 2 months. With the SSD, there is no need for liquid
nitrogen and we hope the s/w will be more user friendly. Some quick
re-training will be needed.
April 2016 - All tools are up. Happy data mining
- Service was performed for both the LEO and Ultraplus SEMs. EBL users of
the LEO should be aware that the beam is now much better aligned and they
may need to do appropriate beam calibration. A new filament has been
installed in the Ultraplus and the tool will be released if it passes the
stability and performance tests. Image quality has been
improved significantly for both SEMs.
30 September 2015 - WATLab new PROMO launched
- See WATLab
Primer. And, take a virtual tour with us, let's go to
Tour 480p or
January 2016 - All tools are up. Happy data mining
- Happy New Year!
1 October 2015 - WATLab promotion - new low rates for SEM and other
tools for the present cycle
- For more details, please see current
July 2015 - Ultraplus resuming normal operation
- The Ultraplus issues have been resolved, and EDX has been
calibrated. As a general operating procedure, please always exit the
EDX software FIRST, before logging out SmartSEM. We are resuming
June 2015 - FEI Quanta Feg 250 Environmental SEM now on line
- The new environmental SEM is now online and a few users have used it
and it appears to be working well. For users who may wish to use this,
please discuss this with Lei for training.
1 June 2015 - Ultra on limited operation
- We have determined that the "lock-up" problem is likely due
to overheating in the Mains PCB in the Ultra.
A temporary fix is in place. The machine is now put back in user
service while we monitor the system. Please discuss this with Nina
if you wish to book time on this machine. We thank you for your
13 March 2015 - Canada's first IBL system to begin installation
- Commissioning of Canada's first ion beam lithography (IBL) system
has began this week. Manufactured by Raith, this
IBL tool will allow true 3D nanofabrication and nanolithography over a
large write-field with an impressive ultrahigh spatial resolution of
sub-10 nm. Like the Helium Ion Microscope (and a few other tools in
WATLab), this is a unique tool in Canada (with just one other older system in
southern U.S. and less than 10 in the rest of the world). This tool
will provide us and all Canadian users new capabilities to begin
constructing novel 3D quantum devices at the nanoscale. This tool is
made possible with funding from CFI, Government of Ontario, and University
of Waterloo. Installation is expected to go on in the next 5-10
11 March 2015 - New ESEM to be installed in early April
- We are preparing our site for installation of a new FEI Quanta FEG 250
system. This environmental SEM will allow us to look at "wet"
samples and we expect to begin installation by early April.
Jan 2015 - Happy New Year! -
The EDX detector has been fixed and reinstalled. Please contact Nina if
you want to use EDX in the near future.
22 Dec 2014 - Merry Christmas and All the Best in 2015 !
- The EDX detector has been repaired and we will reinstall it back in the
LEO in the new year. In late January, WATLab will be installing a
new Environmental SEM system, which will enable our users to look at
materials with a high vapour pressure. We will also be commissioning
a Canada's first Ion Beam Lithography system (one of just 10 systems in
the world) very soon. This IBL system will allow us to write 3D
nanostructures over a large write-field (mm) at 10 nm or less
resolution. We look forward to exciting new science to be achieved
with these new tools. We take this opportunity to thank our users
for their patience and understanding during the various tool commissioning
at qnc this past year, and hope to have their continued support in 2015.
27 Nov 2014 - EDX problem update
- We have sent the EDX detector out for repair and it is
undergoing system testing to assure that it meets specifications. We
expect that it will be shipped back to us in early December.
We thank you for your patience and understanding in this matter.
17 Sep 2014 - EDX problem update
- We are running some more tests on our recent EDX problem.
We are also pursuing a plan B in the event that we could not fix the EDX
system. Those users who urgently need EDX analysis can talk to Nina.
We thank you for your patience and understanding in this matter.
24 June 2014 - LEO resuming normal operation
- We finally resolved the pressure burst issue, and the LEO will be
back in service effective immediately. Please respond any issue to
Nina. We thank you for your patience.
23 May 2014 - LEO to resume partial operation on Monday
- We could only partially rescue the machine and we need to get
some spare parts in order to complete the repair. In the meantime,
the machine can be used under strict "supervised" conditions to prevent
further problems. Please get hold of Yao, Lei or Nina before you
load and unload your samples during your reserved time slot. Thank
you for your cooperation.
21 May 2014 - LEO to resume normal operation on Friday
- Service from Zeiss Canada had created more problems for the LEO
after their service and basically broke our system last week. We
introduced our countermeasure to rescue the system. If all goes
well, LEO will be back in operation tomorrow on 22 May 2014.
12 May 2014 - Zeiss to fix LEO gun column issues
- LEO 1530 will be down till mid next week. to allow the engineer
to fix the gun column issue related to arcing above 10 kV.
9 May 2014 - WATLab website update complete
- Next update in 2 months.
24 February 2014 -
WATLab to begin TEM/FIB service on March 3 at qnc-Metrology
- The newly commissioned TEM & FIB will be put online on March 3.
Please contact us for further details.
5 February 2014 -
WATLab is extending services into the QNC -
The LEO 1530 SEM is now back on line, after a new filament install.
We will gradually reinstate SEM operation back in qnc B707. Please
note that due to security concern, all space in qnc Metrology will be
monitored online with hidden camera.
After many years of trying to get a TEM on campus, we
have finally succeeded in securing a high-performance 200 kV TEM. The Zeiss Libra 200 MC has been installed before Christmas and we have
been doing extensive machine physics studies on the machine while trying
to resolve a number of ongoing issues in the building.
will be gradually rolling out TEM service. Our rate will be very
competitive compared to similar nearby facilities.
13 December 2013 -
WATLab is scheduled to shut down for the Christmas break on
20 Dec 2013 noon - WATLab had an interesting year, with much of tool
installation (including the TEM and FIB at qnc Metrology) now behind us.
We will soon in the new year begin putting some of these tools online.
In the meantime, WATLab wishes everyone a safe and happy holiday, and all
the best for 2014.
1 November 2013 - SEM Status Update-
Both the LEO and Ultra have been down for the past several weeks due to
various failure. We now have an service engineer on site to resolve
these issues. If all goes well, we hope to put at least one of the
systems back in service very soon.
18 September 2013
Internet policy in WATLab
- After taking the LEO back online for just 2 weeks or so, we observed
some unusual behaviour with LEO's User PC. This could be a hidden
virus and we are investigating...
From now on, NO user is allowed to use any of the WATLab's PCs to connect
to the web. If a user gets caught in doing this, he/she will be denied
access permanently! I think it is of interest to all users to try to
keep WATLab's computers clean b/c if one user starts to import virus onto a
WATLab's computer, it will spread to all the PCs of our entire user base.
This is not good for us or for all of our users. I suggest all
users to bring their own laptops and use the wifi. Again, no activity
other than data transfer is allowed on any of the WATLab's computers.
Very soon... we will bolt down the usb key security issue. If you
are not sure how clean your usb key is, please ask us and we will provide
a free blank CD to burn your data. USB key is now the most
vulnerable security risk in our entire data transfer protocol. Thank
6 September 2013
Ultra stage broken
- A user dropped the sample holder onto the stage, which broke the Y
motion drive, rendering the entire SEM useless. The UltraPlus SEM will be down until further notice.
This will be an expensive repair.
As a temporary measure, we
are reactivating the relocated LEO service (now with EDX support) - EBL
feature will take a little bit longer.
that for safety reason, we will be remotely monitoring the activity in the
qnc B707 via an IP camera from C2. The live feed will be password
protected and will not be recorded. This setup will allow us to run
to rescue the user quickly (from C2), should some accident occurs.
5 July 2013 qNC metrology tool deployment update- After much anticipation and delays, we finally have power and the
essential services in the qNC Metrology Lab. At last, we are in a
position to begin tool deployment. We expect that the environmental
conditions to be far from ideal and not to spec as there continue to be
some issues with various support systems in the building. We are
trying to work out these bugs with the renno folks.
If all goes well, we are hoping that the SEM, FIB, SAXS,
XRD (new powder XRD tool), and SQUID will be online by mid August, at
which time we will begin commissioning of the TEM. The TEM
installation is a big job as there will be new optics and new EDX detector
installed on site. The AFM and optical microscope fleet are expected
to be online by late September (once the renno for the respective labs are
In the meantime, we are business as usual here at
WATlab. Have a nice summer and happy data mining!
31 May 2013
- Just one day after the Shops have rebuilt the sample holder for the
Ultra, it has been destroyed! We are extremely unhappy about this.
There are now some users with a heavy hand among us and they are
destroying everything. I'm going to conduct on-the-spot random
testing of all the users. Careless users will have the access
privilege of himself/herself and members of his/her entire group
suspended immediately. A sample holder costs about $10k from Zeiss.
We just could not collect enough user fees to pay for this type of
careless use from one or a few bad users.
The hood for sample preparation and the
SEM bench area are becoming quite untidy with carbon tape and dirty gloves
everywhere. Please clean up the SEM bench area and the hood area
after each session (regardless of whether you use it or not).
If we all do this simple tidying-up, everyone's life will be a bit better.
It only takes a minute or two to pick up after oneself. There will
be a cleaning fee equivalent to 1 hr SEM if these areas are left untidy
for the next user.
6 April 2013
- WATLab has
extended the SEM service for those hard workers (and experienced users!)
who want to do data mining on Saturday morning.
Please note that this time slot will be opened as long as I'm on site to
open the lab door. I'll block off time if I don't plan to be on
site. Please check the booking calendar before showing up.
3 January 2013 - Happy New
Year! May 2013 bring all our users happiness in life and in
We look forward to the installation of the long-awaited TEM (as soon as
the renovation is completed in the various labs in the qNC domain).
We have also expanded our nanomachining capability at WATLab - see
UW Seal with the smallest feature size of 5 nm - perhaps a world
record - written by a helium ion beam.
11 September 12 - LEO now
TheLEO 1530 is now
off-line. We will try to reactivate the system as soon as possible,
upon its relocation to the QNC
building. As a temporary measure, we will train one "senior user",
designated by each group, to use the new UltraPlus SEM now fully
operational at WATLab. We will continue to provide OS service during
this hopefully short period. Thank you for your understanding.
28 August 12 - SEM shutdown on September 8:
We now have a firm date (September 8) that we will
temporarily shut down and store the LEO 1530 till its relocation to the QNC building.
As we have not been told a definite QNC move-in date, we are unsure how
long this shut down will last, hopefully no more than 3 weeks.
Please plan your work accordingly. In the meantime, we will provide
OS SEM service on our other WATLab systems.
2 August 12 -
Anticipated SEM shutdown in mid September:
As the new QNC building is slowly coming online,
we are planning to re-establish the SEM operation there, which will result
in the loss of service for about one month. While we will try
to minimize service interruption as much as possible, we are advising all
users to plan a bit ahead and do your samples now! Relocating a
machine is always a tricky business and sometimes it could unearth
27 June 12 - SEM
down till Monday:
are experiencing some computer issues with the SEM. We have
recovered the system but will need the next two days to stabilize
operation and to do some much needed system maintenance and backup.
If all goes well, we will resume normal operation on Monday July 2.
4 June 12 ***
State-of-the-art ION-TOF SIMS-5 system now fully operational:
We have successfully completed full commissioning of the new
state-of-the-art ION-TOF Static SIMS system, equipped with Canada's first
argon cluster source. The new Ar cluster source enables
precise sputtering of organic films without introducing significant
interlayer mixing and matrix effects. This will be particularly
powerful for organic layer and biomaterial characterization.
WATLab will be accepting SIMS samples on OS basis by July 1.
WATLab is now accepting HIM samples on OS basis. If you have
samples, please contact Lei.
WATLab will begin tool deployment of the FIB and TEM hopefully in July. If the QNC building move-in date is on schedule, then we expect both tools to be
fully commissioned before the end of September. Same deployment
schedule is expected for the SQUID and other tools.
1 May 12 *** EBL &
EDX imaging back to normal operation:
We have traced these problems to a bad switch. Both techniques
should now work properly.
3 Apr 12 *** EBL taken off
line until further notice:
We are experiencing image blackout with the EDX system. A possible
cause could be some sort of communication protocol conflicts between the
EDX and EBL systems. To investigate this further, we need to take
the EBL system off line, fix the EDX and then wait and see if this problem
occurs again. If you are using the EBL system, we apologise
for the inconvenience. We encourage you to use the QNC EBL system in
12 Jan 12 *** Update on QNC tool acquisition and

28 Apr 11 *** SEM resuming
normal operation on 3 May 2011:
A solid state relay on the vacuum board was found to be malfunctioning,
which blocked the power up sequences of the foreline and turbo
pumps. Jacek was able to replace this relay and we will be
conducting machine physics for the rest of this week. WATLab will
resume normal SEM operation on Tuesday, May 3.
23 Apr 11 *** SEM
Down until further notice:
The LEO has suffered a vacuum problem and the foreline pump has
problem starting up. We are investigating the cause. The
system will be down until further notice. Sorry for the
22 Apr 11 *** ORION
The ORION Plus Helium Ion Microscope has
been installed in C2-080 and achieved spec-on-site (with 0.34 nm
resolution) on 19 April, 2010. We expect full operation within the
next two months.
30 Mar 11 *** ORION
Plus Helium Ion Microscope:
Canada's very first Helium Ion
Microscope will be installed in C2-080. The new ion microscope is
offering unprecedented spatial resolution of 0.35 nm with Z contrast for
both hard and soft, conducting and nonconducting materials. This
unique tool is expected to put WATLab and uWaterloo at the cutting edge of
microscopy research and nanosciences.
28 Mar 11 *** EBL
A new version of the Nabity EBL
software is being installed along with a new PC. The EBL system will
be down until further notice. Sorry for the inconvenience.
10 Jan 11 *** Messy
After just one week from startup, we
found that the sample prep hood was once again left with a big mess.
Once the entropy has started, the second law of thermodynamics will take
over WATLab in no time. We have implemented the following
1. From now on, anyone caught leaving a big mess in the SEM, hood,
gold coater, and other areas of WATLab will be charged a clean-up fee
equivalent to 1 h of OS. We will do a spot-check before and
after each user's session to assure compliance. As we just don't
have human resource to clean up after these messy users, chronic messy
users will be banished from WATLab altogether. Each user MUST leave
the workplace in a tidy and clean condition for the next user.
2. Some users still don't know how to use the new
system of the gold coater and proceed to unplug things on their own.
This is NOT acceptable. If you have questions, please come to ask
one of us. If these users cannot follow the protocol, we will
discontinue gold coating service at WATLab.
3 Jan 11 *** Happy
As we start this exciting new year
(celebrating the International Year of Chemistry), we wish to draw your
attention to the new booking system now in place (below). In
the interest of streamlining our operation, accounting and billing will
only be done once a year (from April 2010 to February 2011) - please
inform your boss and this will be done later in February. WATLab
will be completing all the upgrades to the SEM this term, including the
upgrade to the Nabity EBL system. WATLab is looking forward to the
commissioning of the first Helium Ion Microscope in Canada (expected later
in the spring) and of the first Secondary Ion Mass Spectrometry system on
campus (expected later in the fall). Various enhancements of our
other materials science techniques will be made along the way, budget
permitting. With these new and upgraded existing tools, we hope that
WATLab will continue to play a key role in enabling our users to engage in
exciting new research in science and technology in Waterloo, Ontario,
Canada, and beyond in 2011. Happy data mining.
3 Dec 10 *** New SEM
booking system now in place:
The Bookit system will be coming down
on Dec 13. WATLab will not move to its replacement (Outlook
Exchange) b/c it's far too complicated to manage. Instead, we will
use google calendar. Beginning Dec 13, all SEM reservation will be made by
logging in at:
Sign in with the login name watlab.sem
and the appropriate password. Certified users may obtain the new
password from Nina. As we are experimenting with this booking
system, we wish to remind the user that the normal operating hours are 8
am to 4 pm, Monday to Friday. We will block off Operator Service
time slots once the system is stabilized. We hope we could rely on
all of our users to have some patience with each other as we go through
this transition phase. In the meantime, we take this opportunity to
wish you all a happy holidays and all the best in 2011.
21 Oct 10 *** CCEM
There is a one-day microscopy workshop at
Mac on Nov 5, 2010 (Friday). Please see the workshop poster
20 Oct 10 ***
Computer security: We are aware of the ongoing issues with the Raith EBL system at QNC. This has been traced back to a USB stick of
a user infected with the so-called "Chinese virus" that is known
to infect not only
the cpu of any computer but also any EPROM or processor in any
electronic device (including all the electronic boards inside the SEM and
virtually any machine systems at WATLab). This type of virus is also
very difficult to kill once it gets inside a "controller" as antivirus
programs will not work with controllers without the proper OS. This
is a real and very potent threat and can serious damage not just all the
computer systems and machines in WATLab but also all the computers of our
entire user base and their groups. We therefore ask all users to
implement the following counter-measures:
1. Do NOT use any of WATLab
computers, including the USER DATA computer that stores the SEM images,
for any email or messaging or internet or social networking activities.
Under no circumstances should any of the machine computers see the
internet - do not run the browsers on these machines! Anyone caught
with using the browsers on these machines (including the SEM, EDX and EBL
computers) will be banished forever from WATLab. Please bring your
own laptop for these activities and use wireless access.
2. Do NOT bring in any old or
suspect USB stick for transferring data. Please RESERVE (and label)
one new USB stick just for this purpose and don't use it for anything
else. WATLab will also provide blank DVD for writing data, if
needed. The idea is to minimize exposure of our systems to the
3. Please report to us ANY user activity that
does not follow these simple rules. I think we all agree that it is of everyone's interest
to protect WATLab's systems because once affected they will become the
point of infection that spreads the virus to all the computers of anyone
who uses WATLab. This could affect us all very negatively,
especially our graduate students who may be writing their theses.
Thank you for your continued cooperation.
11 Oct 10 *** EBL
upgrade & spectroscopy fleet relocation:
There will be a software (to Version 9 and XP) and hardware upgrade
(control board) to the Nabity EBL system, which will improve the write
speed and off-line design flexibility. We will implement this change
during machine physics time slots and hopefully with minimal service
WATLab is expanding into some recently found space to accommodate the two
new instrument clusters and the RPL. We will also be able to
relocate the spectroscopy fleet to this new space before Christmas.
We expect this should relieve the severe space shortage experienced in all
areas of WATLab.
3 Sept 10 *** Normal
As we begin a very busy fall term, we wish to again remind the user of the
heavy fines for late start and no show. Please have your sample in
hand before making machine reservation to avoid these penalties.
Please also note that we have made an adjustment to the gold coating cost
due to the sharp rise in gold prices and added a surcharge to those who
just use our gold coater and not our SEM.
22 July 10 *** Vacuum problem:
have located the leak and removed this problem temporarily. A new
vacuum readout problem has emerged and we have been working on this last
week. We don't think we have completely resolved this issue but we
will resume normal service starting July 23. Thank you for our
6 July 10 *** Vacuum
chamber pressure has become very poor. We have replaced the turbo
but the problem remains. We are in contact with the service engineer
to find a fix. System will be down until further notice.
Please watch the bookit scheduler.
5 July 10 *** Stage
fixed, but what a messy workplace:
The stage issue has been fixed for now. The system will be available
But I found the clean hood and the SEM general area are always left in a
big mess! I spent 20 minutes cleaning this up this morning and we
will not do this again. From now on, we will check the lab condition
after each user has completed the session. If we find the workplace
is left in a messy and disorganized condition, we will charge a lab
cleanup fee ($50) to the user. Please treat your fellow user with
some respect and leave a clean, tidy and pleasant work environment for the
next user. Thank you very much for your cooperation.
4 July 10 *** Stage
The stage cannot be initialized in the X-Y plane and we cannot use the
system until further notice. We are investigating the cause of the
26 June 10 *** Upgrade
The various upgrades for the SEM/EDX/OIM systems are finally complete.
Zeiss has fixed the miscellaneous air-jack problem and has also replaced
the power control board (that gave the 24 V error). We don't expect
any more service interruption until the filament dies. Our backlog
appears to be improving (down to 2 weeks).
June 10 *** No show and cancellation:
notice a large number of recent no shows and last-minute cancellations.
Please note that there will be heavy fines equivalent to the OS rate
($70/h) or industrial user rate ($165/h) and we will start informing your
boss. Have some respect for other users who may need the time.
We need THREE working days for cancellation. Do not book the machine
unless you have samples in hand.
May 10 *** SEM normal operation:
Backlog is coming down to acceptable level (2 weeks). Filament is on
its last legs. Expect filament replacement soon and minor service
interruption to repair
vibration membranes in the next 2-3 months.
31 Mar 10 *** SEM resuming
The brief SEM pc problem (file saving issue) that
one user encountered this afternoon has been resolved and we are resuming
normal operation. I'll be on site on this good Friday for those
users who decide to do data mining that day. Happy Easter.
May 10 *** Victoria Day Monday:
WATLab will be
open and on normal operation on Monday 24 May 2010.
12 Mar 10 *** Carbon
Those users doing the carbon coating are always leaving the station in a
big mess and creating dangerous situation by not turning off the
controller after use. WATLab will withdraw this self-serve service.
Effectively immediately, users who will need to have their samples
C-coated should submit their samples 5 working days in advance, and we
will do this service for them at a charge of $50 per coating.
17 Feb 10 *** Spot trading:
to have problems with a few users not following the booking rules.
We found some of these users are starting to trade their spots with other
users. This is forbidden because the facility needs to track the
machine usage in case of system breakdown. If the user starts
trading booking spots, then we will lose track of the responsible party
and the type of samples that may be causing the machine problems.
This is also the reason why each user must be trained and certified
individually. There is no substitution. From now on, users
caught trading their spots will be denied access and their entire group
will also be denied access. Zero tolerance.
Given that WATLab does not have an army of facility staff to monitor the
usage and is essentially a self-serve honour system, we hope that the user
will understand that these "strict" facility rules are there to protect
the machines and the general user community. If we allow individual
users to set their own rules as they please, the facility integrity will
degrade quickly, which will lead to chaos that is ultimately bad for all
12 Feb 10 *** Fines for
This morning, both users did not show up for their appointed time slots.
You know who you are! This is a clear sign of lack of respect for
other users, especially when we are all trying to get some time on the
machine to do some work. We have now DOUBLED the fines for no-show
(i.e. twice the rate of OS = $140 per hour) and your boss will be
notified. Please remember that we require 3 working days for
cancellation so that other users can rebook (it's no good if you cancel in
the last minute as the time will still be wasted). If the present
countermeasure does not work, these "no-show" users will be denied future
access and they will be off our grid permanently.
27 Jan 10 *** Booking rules and
Due to the recent surge in the SEM usage, we wish to remind
everyone to treat your fellow user and the machine with respect and to
observe the following protocols:
observe the booking rules, i.e. not counting the current week,
reserve in the coming weeks no more than SIX hours total in no more than FOUR time slots.
THIS MEANS: A user should reserve, in ALL of the coming weeks not counting the present
week (and not per week), the total amount of time not more than 6 hours and the number of
time slots not more than 4, whichever is less. We will be monitoring
this closely and implement heavy fines for users who overbook. Users
who continue to ignore the booking rules will be blocked.
Please show up on time and do not book a time period longer than you need. There will be
fines for users who show up late. Also, try not to leave too many
gaps in between time slots.
3. The fine for "no-show" is charges equivalent
to hours for OS industrial rate, and we will start indicating this on our accounting statement to
your boss - this means your boss will know. We require 3 working
days for cancellation to allow other users to re-book.
We will be creating a new class of users to allow these "senior users" to
access evening and Saturday time slots (when they become available).
Only the most responsible "permanent" users will be given this privilege.
all these measures do not work, then we will start blocking all
11 Dec 09 *** ORF announcement
story at TheRecord.com
10 Nov 09 *** OIM upgrade to
begin at mid-day 1 Dec:
OIM installation will begin on Dec 1 at 1 pm and will continue for the
next two days, if all goes well. We hope that this will be the last
of service interruption for this year. In an attempt to clear some
backlog, experienced users ( = users with at least 20 hours of using the
machine on his/her own) can look out for available walk-in time during the
next few Saturdays. We will unlock these times 12 hours before
Saturday if we are planning to be here in the weekend. Please
note that you must be an experienced user to use these times as we don't
want to babysit new users - we have our own work to do.
27 Nov 09 *** SEM resuming
normal operation on Nov 30:
We have replaced the
broken Varian turbo with a replacement Varian turbo and the vacuum seems
good now. Please go easy on the system.
17 Nov 09 *** System down
due to turbo failure:
The new Varian turbo pump installed just four months ago has failed.
This is a new low even for Varian. WATLab has tried to be a
Varian-free zone but we cannot control what the manufacturer provides in
their systems. We have contacted Zeiss and the engineer is trying to
find us a replacement. The system will be down until we can get this
fixed and we expect to be at least one week. We apologize for any
Update 26 Nov 09:
We have now received a replacement turbo and are waiting for instruction
about the next step. Expect down time no more than one more week.
27 October 09 *** Bad user
One or more users on Monday Oct 26 have left a big
mess in the sample preparation hood and in the lab in general. This
is unacceptable behaviour.
ALL USERS ARE REQUIRED TO LEAVE A "TIDY AND CLEAN" WORKPLACE FOR THE NEXT
We are implementing a penalty to discourage this type of behaviour (the
user will be charged for a big clean up fee and we will inform your boss
about this extra billing). Because of the current high flu season,
we also hope that the user will wash their hands before coming into the
lab to minimize workplace transmission. Thank you very much for your
15 October 09 *** No show:
There has been a number of no-show after the SEM
has been reserved. Please note that WATLab requires 3 working days
for cancellation, and your group will be charged whether you show up for
your booked session or not, as no one else can use the time slot once it
has been reserved. Please keep that in mind when you make your
8 October 09 *** Minor mid-term
The recent rise in the consumable cost, particularly
the price of gold, has given us no choice but to increase the gold coating
charges to $20 per 120-s coat. Please collect eight samples
together and deposit them all at the same time to reduce gold
consumption and the cost to your group.
8 October 09 *** OIM
installation on track:
The expected upgrade to the OIM system (the last of
the summer upgrade) is on schedule - expected to be after mid October.
9 July 09 *** SEM NEW user
The recent upgrade has cost WATLab a considerable amount of cash, none of
which is covered by the user fees. These changes are one-way only,
which means that should the system go down we have no way of going back to
the way we were. Please note the following changes to the present
1. New hand panel:
This front-end input device replaces the ordinary keyboard but it is very
expensive (cost ~$10,000, i.e. one hand panel = 500 keyboards). As
such, we really don't want the hand panel to get dirty or abused because
we won't have a backup due to its high cost. [We have seen serious
abuses to the joystick (cost ~$2000 just for a refurbished one), and our
Shops had to repair it a few times.] From now on, NO
FOOD or DRINK will be allowed into the SEM lab.
Please treat these as very delicate and expensive equipment with respect
as it's NOT a toy. Indeed, we
ask the user to WASH HANDS before handling any of the lab equipment,
particularly the hand panel and of course the microscope.
The practice of hand washing will also help to minimize the risk of flu
transfer via WATLab equipment during the flu seasons and we hope the user
will appreciate this extra health and safety protection practice for all.
Any user caught with dirty hands, food or drink or leaving a messy work
place for the next user will risk having his/her access revoked.
2. New SmartSEM software: The user will
find all the icons looking different. But all the functions are
still there while they may be residing in different places. The
system now operates in XP Pro environment with dual monitor support.
Once we familiarize ourselves, we will recommend the best setup to
proceed. In the meantime, please do not
hesitate to ask and do NOT explore the system on your own (because things
may get messed up and we don't know how to fix it).
capabilities: We will roll out the new capabilities as we fully test
out these features to assure robustness. Please stay with
something that you know. For now, the user will find the beam aligned a lot better than before, with the current improved by over 50%.
We think the user will like the new upgrades as these will not only make
the machine even more user friendly but also improve the image quality.
Please be patient with us and with your fellow user as we are adapting to
the new system. Thank you very much for your kind cooperation.
28 August 09 ***
EDX Genesis Version 4.61 now in place:
The new EDX software (Genesis V 4.61) has now been
installed and appears to be functioning normally. There is only very
minimal front-end change noticeable to the user, but the software is
claimed to have the most stable engine.
The OIM upgrade is next and expected to be sometime in mid September,
which will complete the series of summer upgrades to the SEM system,
making it remaining to be a state-of-the-art and most advanced
6 August 09 ***
CFI UW News Release:
WATLab to lead SMO research - First Helium Ion Microscope and RPL to come
to Canada... The HIM is the most powerful microscope on Earth and UW
users should be among the first to take advantage of this unique facility
- the second-generation HIM! We will be one of less than 20 sites
worldwide, and the only Canadian site, to have this HIM instrument.
12 July 09 *** Booking rule #3: It has come to our attention that some users are ignoring the advance
booking rule. Please remove any extra booking slots, in keeping of
Rule #3 below to allow all users a fair chance of access to the system. All users should
only reserve NO more than six hours or 3 times slots TOTAL (and not per
week) in the coming weeks. If we cannot convince the user to do this voluntarily, we may need to
implement a more draconian measure.
4 September 09 ***
Resuming SEM on September 15:
The problem has been resolved and the SEM is
functional. In the next few days, we will however be investigating
the cause of the lock-up and will see if we can develop some possible
safety measures to prevent similar types of lock-up and failure in future.
WATLab will resume SEM service on September 15.
31 August 09 ***
SEM DOWN until further notice:
The y-motion axis was broken this morning. We
will try to get a replacement in as soon as possible. In the
meantime, the system is off-line.
30 July 09 *** Machine
We have been alerted that there is a potential problem related to clicking
of relays on one of the boards. We are looking into this problem,
and Zeiss engineers have been contacted.
30 July 09 *** OIM/EDX upgrade
The OIM/EDX upgrade is on order and is expected sometimes in the next few
weeks. Instead of unnecessarily blocking off access for a whole
week, we will just "bump off" the users during the two days of the
installation. ALL USERS: Please be aware
that your booking may get override by the installation on very short
notice. The upgrade
will include new EDX software, and a new CCD OIM camera plus software.
More to come...
6 July 09 *** SEM overhaul NOW:
Zeiss engineer will be on site starting July 7 to implement the much
anticipated SEM upgrades, and the system will be down for about a week.
The user will see a significant improvement in the way the SEM works and a
brief "re-training" will be needed before granting access.
After the upgrade, please book as normal but CONTACT ONE OF US BEFORE
STARTING YOUR SESSION. We will have expert users standing by to
provide some help.
present SEM upgrade will include: New SmartSEM software, new
hand-panel for image control, new high current mode, plus other less
obvious items (new PC and new turbo). This upgrade will bring the
system back to "state-of-the-art" status, after 10 years of continued
heavy usage as the singular most important tool on campus in promoting
advanced materials research at Waterloo and nearby local industries.
This will be the first of a series of upgrades to the
existing WATLab facilities... There will be minor upgrades to the
EDX/OIM system to follow in the next two months after the SEM returns to
stable normal operation.
15 May 09 *** Restarting EBL
service: EBL users have now agreed to a new processing protocol to minimize machine
contamination. Machine conditions will be closely monitored during
this restart phase.
May 09 *** WHY did Noah build the Ark?
The ESCALab was once again flooded for the second time in 3 years by shady
plumbing infrastructure and years of poorly maintained building practices
in C2. This time the pouring water was fast and
furious, yellow in colour and smelling bad. It took Plant Op several
people and seven hours to unclog the main drainage to resolve this
flooding problem. We are accessing the potentially huge damage to
the Spectromicroscopy Lab due to the sewage water and bracing ourselves
for long lost time and large repair bill. Expect
significant down time to the ESCA service...
May 09 *** USER DATA folder cleanup:
The USER DATA folder is down to 4 GB free space now. All USERS:
Please remove all the image files as soon as possible. Thank you for
Apr 09 *** NO after-6pm access:
In order to keep a closer eye on the machine and hopefully keep it alive
till the overhaul, we will not allow access after 6 pm until further
notice. Please book time in the normal hours. We have deleted
all after-hour bookings.
Apr 09 *** SEM has been fixed. Resuming normal operation onThursday
Please note that this is a temporary fix only. In case the system
crashes or the program freezes again, please come to get one of us.
If we are not nearby, please leave a note (describing what has happened)
and your extension so we can contact you later. The accounting
software will log out automatically and you won't be charged. Please
do not power down the hardware or the software because (a) it may cause
further damage to the system and (b) it's easier to diagnose the problem. Thank you for your patience
and cooperation. Also, please note that
overhaul is still coming in 3-4 weeks. Stay tuned.
Apr 09 *** EBL off-line until further notice:
Our countermeasure has failed. We are suspending all EBL service
effective immediately to see if we can minimize further contamination to
the SEM. We recommend all existing EBL users to use the UWO facility
in the meantime. We ask all remaining users to check their sample
cleanliness carefully, and any user found with questionable samples will
risk having their account deactivated.
Mar 09 *** SEM contamination issue: We have detected some narrowing of the smaller slits, which suggests
possible contamination from some of the users' samples. This is not
good for the users because it will also mean that all EDX quantification
could be off - not to mention the high cost of replacing the slit. Please be sure that your samples are clean and
free from materials that can be easily evaporated by electron beam
bombardment. Users working with photoresists and other porous materials
should definitely check their samples. If you are not sure about
your samples, please check with us for a possible handling solution.
We will be doing spot-checking in the next few weeks, and if we find some
users knowingly risking the machine, we will revoke their WATLab access to
protect the rest of our user base.
Mar 09 *** SEM upgrade planned: We have entered into serious negotiation with Zeiss and EDAX to perform a
long overdue system overhaul to repair both the software and some of the
hardware (hand panel, turbo, pc) in the SEM, EDX and OIM systems. It
is anticipated that work will begin early or mid May and the machine is
expected to be down for about a week if all goes well. Please be
advised that user booking may get overridden by this service.
13 Mar 09
*** USER FEES INCREASE: Due to the increase in service cost and the uncertain financial
outlook of WATLab, the USER FEES WILL GO UP effective 2009. Please
note the new SEM user fees ($40/h for Certified Users
and $70/h for OS services) and the new cap ($4000 for every six months). If you do not like the fees hike,
please (a) talk to your Department Chair and your Dean and get them
to provide direct support (not just spiritual one) to WATLab. Kind
words and nice gestures don't pay the bill.
***Despite its perceived importance and its heavy usage from all major departments on campus, WATLab sadly does
not receive a single dime from UW Administration. We no longer have sufficient funding to continue to
subsidize (yes, subsidize!!!) its expensive on-going operating cost,
and will begin to implement a user fees structure that
more accurately reflects the actual cost of using these expensive machines on a
