CZT imaging detectors for ProtoEXIST
We describe the detector development for a balloon-borne wide-field hard X-ray (20 – 600 keV) telescope, ProtoEXIST. ProtoEXIST is a pathfinder for both technology and science of the proposed implementation of the Black Hole Finder Probe, Energetic X-ray Imaging Survey telescope (EXIST). The principal technology challenge is the development of large area, close-tiled modules of imaging CZT dete...
متن کاملAdvanced Readout ASICs for Multielement CZT Detectors
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...
متن کاملA "Bioscope" system using double-sided silicon strip detectors and self-triggering read-out chips
The components and the design of a 640 by 640 channel radiation detection system based on double-sided silicon strip detectors and self-triggering read-out chips are presented. The system has been designed for applications in autoradiography and X-ray imaging in medicine, biology and other fields. Images and results from first tests of the system are shown.
متن کاملEnergy resolution improvement in room-temperature CZT detectors
We present methods to improve the energy resolution of single channel, room-temperature Cadmium-Zinc-Telluride (CZT) detectors. A new preamplifier design enables the acquisition of the actual transient current from the crystals and straightforward data analysis methods yield unprecedented energy resolution for our test-detectors. These consist of an eVCAPture Plus crystal as standard and 1 cm c...
متن کاملAn Investigation on Cooling of CZT Co-Planar Grid Detectors
The effect of moderate cooling on CdZnTe semiconductor detectors has been studied for the COBRA experiment. Improvements in energy resolution and low energy threshold were observed and quantified as a function of temperature. Leakage currents are found to contribute typically ∼5 keV to the widths of photopeaks.
