Multi-crystal analyzer detector system for use as detector in synchrotron for analysis of powders, has beam limiting device, which divides overall beam into individual beams and absorbs scattered radiation

The multi-crystal analyzer detector system has two beam limiting devices, two collimators (2,3) and detectors, which are connected with evaluation devices. The beam limiting device divides an overall beam into individual beams and absorbs the scattered radiation. The beam limiting device comprises a firmly mounted diaphragm with an exchangeable diaphragm (8,11) for each individual beam. The individual beams enter into a collimator path. The former beam limiting device and the former collimator are made of tungsten or tungsten alloys. An independent claim is included for a method for x-ray diffractometry of powders
