KMC-2 Diffraction

KMC-2 Diffraction

The instrument Diffraction is a 6-circle goniometer in psi-geometry. The sample is mounted on a motorized stage that allows movement in all directions. Two detectors are available: A scintillation detector (Cyberstar) and an area detector (Bruker Vantec). 2Θ angles up to 140° are accessible with the area detector. The instrument is located at the KMC-2 beamline, which provides X-ray radiation with very stable energies in the range between 4 and 14 keV. This combination covers most scattering requirements.

A high temperature vacuum chamber is available to perform in-situ experiments. The chamber is equipped with a Be-Dome and provides vacuum down to 10-6 mbar also at high temperatures.
