Photo of the XEOL cryostat integrated at the end-station of the beamline P65 of PETRA III
Photos (left) of the optical head and the SDD X-ray fluorescence detector in front of the XEOL cryostat and

The new XEOL setup is suitable for routine steady state XEOL measurements and for simultaneous XEOL and X-ray absorption spectroscopy characterizations. The key components of the setup include a state-of-the-art optical spectrograph, equipped with a triple grating turret, and a Si CCD camera and an (In,Ga)As photodiode array detectors, and a modified He-flow cryostat with three X-ray windows and one optical window.
