A generation of high performance front-end and read-out ASICs customized for highly segmented CdZnTe sensors is presented. The ASICs, developed in a multi-year effort at Brookhaven National Laboratory, are targeted to a wide range of applications including medical, safeguards/security, industrial, research, and spectroscopy. The front-end multichannel ASICs provide high accuracy low noise pream...

Abstract In this work, Cu-Zn-Sn (CZT) is co-electrodeposited onto a flexible Mo substrate exploiting an alkaline bath (pH 10). The plating solution studied by cyclic voltammetry, highlighting the effects of potassium pyrophosphate (K 4 P 2 O 7 ) and EDTA-Na on electrochemical behavior stability metallic ionic species. optimized synthesis results in homogeneous precursor layer, with composition ...

Infrared cooled photodetectors must operate at higher temperatures to reduce their size, weight and power consumption (SWaP context). Their stability image quality are then challenged by extra electrical activity of crystal defects. Knowledge defect populations is mandatory improve the material epitaxial Hg1−xCdxTe (MCT) active layer Cd1−xZnxTe (CZT) substrate. Positron annihilation spectroscop...

Abstract Background The digital cadmium–zinc–telluride (CZT)-based SPECT system has many advantages, including better spatial and energy resolution. However, the impacts of different acquisition reconstruction parameters on CZT quantification might still need to be validated. This study aimed evaluate (the main window time per frame) number iterations, subsets in iterative reconstruction, post-...
