High channel density germanium detector demonstrator for high throughput X-ray spectroscopy
2017
Multi-element germanium detectors for X-ray fluorescence are widely used in synchrotrons. A demonstrator of highly segmented germanium detector fitted with cube preamplifier [1] for X-ray spectroscopy has been reported in this paper after a first demonstrator gave encouraging results a few years ago [2]. This demonstrator has nineteen hexagonal pixels of 2 mm pitch fitted with cube preamplifier. All the nineteen channels of this demonstrator were tested and found to be working with analogue chain electronics. Eight central channels of this demonstrator were calibrated using digital pulse processor, namely Xspress3 [3] and were exposed to beam. The beam size used was 20 µm × 20 µm so that the beam can be focused at the center of pixels and a raster scan amongst pixels can be done.
