The P22 experimental hutch hosts several XPS instruments. The work horse setup is a high-resolution Hard X-ray Photoelectron Spectroscopy (HAXPES) instrument.

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.
