The Cadmium Zinc Telluride (CZT) Detector Array Innovation Pathway
ثبت نشده
چکیده
This pathway describes the development of soft gamma-ray/hard x-ray detector arrays at NASA’s Goddard Space Flight Center (GSFC, or Goddard), through a collaboration between the gamma-ray spectroscopy group and the detector branch. The Cadmium Zinc Telluride (CdZnTe, or CZT) detectors which resulted from this decade-long development were first flown on the wildly successful SWIFT mission in 2004, and have since enabled a whole class of imaging applications in the hard X-ray/soft gamma-ray range. The CZT detectors filled a long recognized need for a room temperature semiconductor capable of high resolution imaging and spectroscopy in this particular waveband.

Cadmium Zinc Telluride is an emerging material for room temperature radiation detectors. In order to optimize the performance of these detectors, it is important to determine how the electronic properties of CZT are related to the presence of impurities and defects , that are introduced during the crystal growth and detector fabrication. At the Sandia microbeam facility IBICC and Time Resolved ...

UNLABELLED The purpose of this study was to evaluate a small semiconductor-based gamma camera that may have applications in scintimammography. METHODS A small cadmium zinc telluride (CZT) detector was evaluated. The detector had a field of view of 20 x 20 cm with detector elements of 2.5 x 2.5 mm in size. Both short-bore (35 mm) and long-bore (50 mm) collimators, matched to the geometry of th...
متن کاملDigital fast pulse shape and height analysis on cadmium-zinc-telluride arrays for high-flux energy-resolved X-ray imaging.
Cadmium-zinc-telluride (CZT) arrays with photon-counting and energy-resolving capabilities are widely proposed for next-generation X-ray imaging systems. This work presents the performance of a 2 mm-thick CZT pixel detector, with pixel pitches of 500 and 250 µm, dc coupled to a fast and low-noise ASIC (PIXIE ASIC), characterized only by the preamplifier stage. A custom 16-channel digital readou...
