Multi-element X-ray detection module

Function

Detection and spectrometry of hard X-ray radiation with the possibility of assembling of large area position-sensitive detectors.

Description

The module is a hybrid integrated circuit, manufactured by the thick film technology. 32 CdZnTe-detectors are fixed on the top surface of the ceramic substrate; these detectors provide high X-ray detection efficiency and allow operation under moderate cooling (to 3040) ). The design of module enables tight mounting for composing of detection plane the required size. The module is currently under development for the coded mask X-ray telescopes for the SRG/eROSITA/Lobster project.
