Abstract
The KMC-1 is a soft x-ray double crystal monochromator beamline for the energy range between 2 and 12 keV. The bending magnet beamline as well as the experiment are under UHV-condition. It incorporates high indexed Si-crystals for high resolution and it is primarily used for HAXPES experiments employing the HIKE (High Kinetic Energy Photoelectron Spectroscopy) chamber.
Highlights
The crystal monochromator beamline KMC-1 (Schaefers et al, 2007) at a BESSY II bending magnet covers the energy range from soft (2 keV) to hard x-rays (12 keV) employing the n,n double crystal arrangement with constant beam o set
The multipurpose beamline is used for techniques such as hard x-ray high kinetic photoelectron spectroscopy (HIKE or HAXPES), (Bio)-EXAFS, NEXAFS, absorption, re ection and uorescence spectroscopy
HAXPES with a total instrumental resolution of about 150 meV is possible at selected energies
Summary
The crystal monochromator beamline KMC-1 (Schaefers et al, 2007) at a BESSY II bending magnet covers the energy range from soft (2 keV) to hard x-rays (12 keV) employing the n,-n double crystal arrangement with constant beam o set. Beamline and monochromator have been optimized for high ux and high resolution. The beamline and experiment are under UHV-condition. HAXPES with a total instrumental resolution of about 150 meV is possible at selected energies. The beamline is not permanently equipped with a particular experimental station but rather varying user experiments are connected to it according to the beamtime schedule. Based on the allocated beamtime the HIKE end station is the main user of the KMC-1 beamline (Gorgoi et al, 2009)
