Energy and position resolution of a CdZnTe gamma-ray detector with orthogonal coplanar anodes [PDF]
, 1999 We report on the simulation, construction and performance of prototype CZT imaging detectors employing orthogonal coplanar anodes. These detectors employ a novel electrode geometry with non-collecting anode strips in 1D and collecting anode pixels ...

Denoising data acquisition algorithm for array pixelated CdZnTe nuclear detector
Open Physics, 2019 Traditionally, the binary search method is used to collect the denoising data in the array pixilated CdZnTe nuclear detector. Due to the high dispersion of the data itself, the acquisition efficiency is low and the acquisition result has a large error. A

Illumination response of CdZnTe [PDF]
SPIE Proceedings, 2011 CdZnTe (CZT) semiconducting crystals are of interest for use as room temperature X- and γ-ray spectrometers. Several studies have focused on understanding the various electronic properties of these materials, such as the surface and bulk resistivities and the distribution of the electric field within the crystal. Specifically of interest is how these

Effect of Deep-Level Defects on the Performance of CdZnTe Photon Counting Detectors
Sensors, 2020 The effect of deep-level defects is a key issue for the applications of CdZnTe high-flux photon counting devices of X-ray irradiations. However, the major trap energy levels and their quantitive relationship with the device’s performance are not yet ...
