Current status

Certain features of the beamline and endstations are still actively being worked on.
Take these comments into account when planning your experiment

 

Photon energy
  • Specifications: 10-1000eV
  • Comments: Commissioned for high flux 10-250eV for high. 250-1000ev possible through EPU wiggler mode with reduced flux.
Gratings:
  • Specifications: 4 gratings, 4000 lines/mm for cNIM mode and 92, 800 and 2400 lines/mm for the cPGM mode.
  • Comments: 800 lines/mm grating installed and commissioned. 4000 lines/mm grating installed not commissioned.
Polarisation
  • Specifications: Fully elliptically polarising undulator
  • Comments: Horizontal and vertical linear polarisation commissioned. Circular polarisation under commissioning.
Cooling
  • Specifications: < 20K at sample position
  • Comments: 18K achieved at sample position using high LHe flow. 30K stable temperature with resonable LHe flow.
Variable sample temperature
  • Specifications: Stable variable temperature between 20K-300K at sample position
  • Comments: 30K achievable using LHe, 80K using LN2 and RT without cooling attached. Variable temperature possible during LHe cooling with counter heating coil at cold tip. Temperature stability needs further commissioning.
Spin ARPES
  • Specifications: 3D Spin ARPES.
  • Comments: Part of second end station, under commissioning.
Higher order suppression
  • Specifications: Quasi periodic undulator, solid state filters and gas filter.
  • Comments: Only Quasi periodic undulatory is commissioned and available for higher order suppression.
