  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.  Please consult 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. 


10 Feb 2017 - LEO resuming  normal operation -  Ultra resuming limited operation - 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.

Established with funding support from Canada Foundation for Innovation and the Province of Ontario in 1999, WATLab is the first multidisciplinary materials research centre in Canada's Technology Triangle.  WATLab offers a complete toolset for advanced materials research and emerging technology development.  Most of our instrument systems are state-of-the-art and some are unique in Canada, and they include:

  • all areas of microscopy and diffraction [Zeiss Libra 200MC TEM, Zeiss Leo 1530 and UltraPlus FESEMs (with EDX/OIM), FEI Quanta Feg 250 ESEM (with EDX), Zeiss Orion Plus HIM, Omicron VT-STM, DI D3500 Nanoman and Asylum BIO-3D AFMs, Olympus LMs; Anton Paar SAXS, PANalytical X'pert Pro MRD HR-XRD and MPD Powder XRD] - Contact Nina or Saurabh  for SEM & XRD; Lei for AFM, HIM, FIB & TEM; Anisur for LM, XRD & SAXS.

  • spectromicroscopy and spectroscopy [VGS ESCALab 250 Imaging ESCA, IONTOF SIMS-5, PE LS55 PL, PE Lambda 35 &1050 UV-Vis, Bruker Senterra-2 Raman, Bruker Tensor 27 FTIR] - Contact Jung Soo for ESCA & SIMS; Lei for Auger; Anisur for optical spectroscopies

  • bulk characterization [QD Dynacool PPMS, QD SQUID-VSM MPMS] - Contact Anisur;

  • lithography and nanomachining [Nabity and Fibics EBLs, Raith IBL, IMP Xpress Maskless OL, Zeiss Auriga FIB-SEM, DI Nanoman NL, Fibics NPVE];

  • wet and dry materials synthesis (all areas); and

  • rapid device prototyping (all areas). 

We offer pay-per-use service for both academic and industrial users at competitive rates, with our expert operators providing sample characterization measurement (and analysis).  For a selected number of tools (e.g. SEM), we also provide training to allow the users to access the tools through a self-serve booking system. 

To submit samples for analysis, please fill in Form A (and Form B for University of Waterloo users) above, and contact the respective technical specialists.  For all other enquiries and guided lab tours, please contact manager .
