An efficient X-ray spectrometer based on thin mosaic crystal films and its application in various fields of X-ray spectroscopy

Abstract

X-ray optics with high energy resolution and collection efficiency are required in X-ray spectroscopy for investigations of chemistry and coordination. This is particularly the case if the X-ray source emits a rather weak signal into a large solid angle. In the present work the performance of a spectrometer based on thin mosaic crystals was investigated for different spectroscopic methods using various X-ray sources. It was found that, even with low-power X-ray sources, advanced high-resolution X-ray spectroscopy can be performed.
