ictran / / Instrument Status

Hello Kratos-Supra users,

The Supra has gone through a maintenance service by Kratos engineers and now is open for user operations. The following functionalities are working:

  1. XPS and other advanced-XPS modes: Small, selective-area (SA-XPS), Angle-resolved (AR-XPS), Low intensity (LI-XPS), Valence band XPS
  2. XPS parallel imaging (with spatial and chemical resolution ~ 1 um)
  3. UPS, including AR-UPS
  4. Monoatomic and cluster mode GCIS for sample cleaning and depth-profiling with other spectroscopic techniques
  5. Glovebox sample preparation and transfer for air-sensitive samples
  6. In-situ programmable heating/cooling, multi gas dosing in the SAC and in-vacuo in the SSS
  7. Multi-layer, monolayer and sub-monolayer deposition with a programmable multi-pocket mini-e-beam in the SSS and transfer to the Supra for analysis.

In addition, the control PC has been upgraded to Windows 10. The ESCApe database has been fixed. An updated SOP is placed on the PC desktop.

If you want to get trained on either the basic or advanced operations of the instrument, please sign up to the waiting list below:

Hello Kratos-Supra users,

The X-ray source needs a filament replacement. We have reported and been waiting for a service visit by a Kratos engineer to fix the source and other issues. I will cancel the sessions currently reserved for the instrument.
I will send out another update when the instrument is back up online.

Thank you,
Ich Tran
