Vacuum-compatible photon-counting hybrid pixel detector for WAXS, XRD and XRR in the tender X-ray range — •Dieter Skroblin¹, Levent Cibik¹, Benjamin Lüthi², Swenja Schreiber¹, Maximilian Luttkus¹, Alexander Schavkan¹, Mika Pflüger¹, and Michael Krumrey¹ — ¹Physikalisch-Technische Bundesanstalt (PTB), Abbestraße 2-12, 10587 Berlin, Germany — ²DECTRIS Ltd., Neuenhoferstrasse 107, 5400 Baden, Switzerland

A vacuum-compatible photon-counting hybrid pixel detector has been installed in the UHV reflectometer of the four-crystal monochromator beamline of the Physikalisch-Technische Bundesanstalt (PTB). The setup was developed in cooperation with Dectris Ltd. and is based on the PILATUS3 100k module. The quantum efficiency, homogeneity, angular dependence and linearity of the new detector have been investigated. First results of the performance in wide-angle X-ray scattering (WAXS), X-ray diffraction (XRD) and X-ray reflectometry (XRR) are presented.
