Recoil of constituent nuclei from neutron elastic scatter in pixelated, 3-D CdZnTe gamma-ray detectors is detectable given current low energy thresholds. Fast neutrons are attenuated by CdZnTe detectors via outscatter and measured gradients in neutron interaction rates across detector pixels that enables 1-D fast neutron source localization through a maximum likelihood estimator. Experimental results...
A new portable gamma-ray imaging spectroscopy system using three dimensional position-sensitive CdTeZe has been built at the University of Michigan. This system uses a first generation digital VAD_UM ASIC jointly developed by Integrated Detector Electronics AS (IDEAS) and the University of Michigan and allows four 20 × 20 × 15 mm3 CdZnTe detectors to be simultaneously read out in either a full readout...
Mercuric iodide single crystals have been used successfully as gamma radiation detectors for many years. Recently a different growth method called `seeded homoepitaxy' has been studied. This method has the advantage of growing detector-sized volumes with a thickness of about 10mm in a highly accelerated timeframe. The electronic transport properties of a mercuric iodide detector have been shown to...
