``XRD``: The X-Ray Diffraction Chamber
======================================

Overview
--------

The XRD chamber is designed to perform all kinds of XRD and hRIXS experiments on solid targets.


Detector Ring
~~~~~~~~~~~~~

The XRD hosts a detector ring on which are located various detectors (antenna, diodes, APD, ...). The detector ring is rotated by the *DRY* motor.

A table of installed detectors is available at https://syncandshare.xfel.eu/index.php/apps/files/files/11825393?dir=/SCS/Instrument

The details of the detectors arrangement, as of 15.11.2022, can be found in https://in.xfel.eu/elog/SCS+Instrument/3645.
Diode 1 is an antenna used for coarse timing.
