X-ray Energy Response of Mercury Cadmium Telluride Near-infrared Detector Arrays
A technique involving Fe X-rays provides a straightforward method to measure the response of a detector. The detector’s response can lead directly to a calculation of the conversion gain (e ADU), as well as aid detector design and performance studies. We calibrate the Fe X-ray energy response and pair production energy of HgCdTe using 8 HST WFC3 1.7 μm flight grade detectors. The results show t...
متن کاملMonte Carlo and least-squares methods applied in unfolding of X-ray spectra measured with cadmium telluride detectors
Spectra of calibration sources and X-ray beams were measured with a cadmium telluride (CdTe) detector. The response function of the detector was simulated using the GEANT4 Monte Carlo toolkit. Trapping of charge carriers were taken into account using the Hecht equation in the active zone of the CdTe crystal associated with a continuous function to produce drop of charge collection efficiency ne...
متن کاملEvaluation of a small cadmium zinc telluride detector for scintimammography.
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 کاملThe Cadmium Zinc Telluride (CZT) Detector Array Innovation Pathway
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 200...
متن کاملImaging properties of small-pixel spectroscopic x-ray detectors based on cadmium telluride sensors.
Spectroscopic x-ray imaging by means of photon counting detectors has received growing interest during the past years. Critical to the image quality of such devices is their pixel pitch and the sensor material employed. This paper describes the imaging properties of Medipix2 MXR multi-chip assemblies bump bonded to 1 mm thick CdTe sensors. Two systems were investigated with pixel pitches of 110...
