XANELS XPS ultra high vacuum system [project 043]
UHV system designed to operate as both a stand-alone device or as an end station in synchrotron installations. A key feature of the system is the ability to handle volatile samples throughout via efficient liquid nitrogen cooling. This is a fundamental design feature of this specific system for reproducible studies of volatile mineral samples.
The system is a multi-user XANELS and XPS facility characterised by the following features:
- High throughput photoemission energy analyser
- NEXAFS detector (partial electron yield and total fluorescence yield)
- Sample cooling to 120K (using LN2) or ~40K (using LHe)
- Flood gun and dual-anode X-ray source
- Ability to transfer samples at 120K
- Rotary distribution chamber allows sample transfer to 8 chambers
- Fast sample entry load-lock with glove-box
- Sample fracture chamber and storage chamber
- Preparation chamber for sputtering, evaporation etc.
- Ability to be upgraded via add-on chambers using spare-ports
- Motorised sample manipulators and user friendly control system
- Support frame with a large range of adjustment, to allow SXSI to be mounted on the complete range of NSRRC soft X-ray beamlines, and on the Australian Synchrotron.
