XRD X-Ray Diffraction Chamber

The X-ray diffraction endstation (XRD) is dedicated to study solid state systems for example quantum and battery materials using elastic and inelastic X-ray scattering techniques. The sample is mounted on a 6-circle goniometer and can be cooled down to cryogenic temperatures. The sample is kept in ultra high vacuum down to 10-8 mbar. The chamber is equipped with a detector ring with rotation axis co-axial with the sample goniometer and able to make full 360 degree rotation. Currently a multi-channel plate (MCP), an avalanche photodiode (APD) and a Si- diode are available on the detector ring.  The chamber can operate in combination with the hRIXS spectrometer.
