The FT (peak bolometric photon flux) vs. Ep (peak energy) plane is a powerful tool to compare the burst populations detected by different detectors. Detector sensitivity curves in this plane demonstrate which burst populations the detectors will detect. For example, future CZT-based detectors will show the largest increase in sensitivity for soft bursts, and will be particularly wellsuited to s...

CdZnTe (CZT) has made a significant impact as a material for room-temperature nuclear-radiation detectors due to its potential impact in applications related to nonproliferation, homeland security, medical imaging, and gamma-ray telescopes. In all such applications, common metals, such as gold, platinum and indium, have been used as electrodes for fabricating the detectors. Because of the large...

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 ...

The detector material Cadmium Zinc Telluride (CZT) achieves excellent spatial resolution and good energy resolution over a broad energy range, several keV up to some MeV. Presently, there are two main methods to grow CZT crystals, the Modified High-Pressure Bridgman (MHB) and the High-Pressure Bridgman (HPB) process. The study presented in this paper is based on MHB CZT substrates from the comp...

The performance of the Radionuclide Aerosol Sampler/Analyzer (RASA) under high-activity conditions has been evaluated to maintain and protect operations International Monitoring System (IMS) radionuclide stations. Station measurements following Fukushima Daichi accident 11 March 2011 have combined with laboratory understand how quality made using RASA High-Purity Germanium (HPGe) gamma-spectrom...

McMaster University, Canada While mammography is the gold standard for breast cancer screening, it suffers from poor sensitivity in women with dense breast tissue. Both breast MRI and molecular breast imaging (MBI) have been used as secondary imaging techniques. However, breast MRI suffers from low specificity and low sensitivity in MBI. A CZT based detector system has been developed with the g...

We have investigated charge sharing among the anode strips of a CdZnTe (CZT) detector using a 30μm collimated gamma-ray beam. We compared the laboratory measurements with the predictions from our modeling of the charge transport within the detector. The results indicate that charge sharing is a function of the interaction depth and the energy of the incoming photon. Also, depending on depth, a ...

At DTU Space, a 3-D CdZnTe (CZT) drift strip detector prototype of size 20 mm $\times4.7$ notation="LaTeX">$\times20$ has been developed. It demonstrated excellent submillimeter position resolution (<0.5mm) and energy (<1.6%) at 661.6...
