In experiment hutch 3, a high-resolution Hard X-ray Photoelectron Spectroscopy (HAXPES) instrument is installed, located at 94 m from the source.
PLEASE NOTE:
The HAXPES instrument in hutch 3 will be relocated to beamline P22 in the summer shutdown 2018. Please select P22 for the submission of new proposals.
In addition to the beamline optics described for hutches 1+2, a post monochromator is available for high-resolution spectroscopy with <100 meV energy resolution. For polarisation dependent experiments, a single stage of the P09 diamond phase retarder is used to produce left/right circular polarised light.
Photoelectrons with up to 10.5 keV kinetic energy can be measured in different experimental geometries by means of a SPECS Phoibos 225 HV hemispherical analyser with a delayline detector. For angle-resolved studies or high-transmission requirements, an optional wide angle lens (+- 30 degrees acceptance) can be adapted to the analyzer.
The analysis chamber is equipped with a custom made high-precision fully motorised OMICRON 5-axis manipulator with LHe cooling. The instrument is mounted on a motorised high-precision XZ-platform consisting of a monolithic granite support which is adjustable in height and can be translated transversely relative to the incoming X-ray beam with very high precision.
