Spectral signature of near-surface damage in CdTe X-ray detectors

Grimm, O.

Knowledge of the response matrix of an X-ray detector is an important prerequisite for efficient use. This matrix is usually complicated due to the multitude of effects that determine the photon interaction and energy detection processes. Consequently, assembly of a response matrix often proceeds via simulation, modelling features of the detector …

Changes in detection characteristics of CdTe X-ray sensors by proton irradiation

Commichau, V.; Grimm, O.; Bednarzik, M. +1 more

This paper reports on the performance changes in CdTe:Cl semiconductor X-ray detectors seen after irradiation with 50 MeV protons up to a fluence of 1.6 ṡ10¹¹cm^-2. The rationale for the irradiation parameters is described. Performance was quantified before and after irradiations by obtaining X-ray spectra with a barium-133 ra…
