Spectroscopy on Thick HgI2 Detectors: A Comparison Between Planar and Pixelated Electrodes

Thick mercuric iodide (HgI 2 ) detectors are investigated as potential room temperature gamma-ray spectrometers. By using pixelated anodes the induced charge on the electrode is dependent mainly on electron movement and is almost independent of the depth of interaction. Moreover, by reading out the planar cathode signal simultaneously, the depth of interaction can be determined and any effects ...

Optimization of an ultra-high-resolution rectangular pixelated parallel-hole collimator with a CZT pixelated semiconductor detector for HiRe-SPECT system

Introduction: In nuclear medicine, the use of a pixelated semiconductor detector such as CZT is an of growing interest for introducing new devices. Especially, the spatial resolution can be improved by using a pixelated parallel-hole collimator with equal holes and pixel sizes based on the pixelated detector. The purpose of this study was to compare the effect of pixelated and ...

3-D position sensitive CdZnTe gamma-ray spectrometers

Two 3-D position-sensitive room temperature semiconductor c-ray spectrometers have been built using 1 cm3 cubic CdZnTe crystals. The lateral coordinates of c-ray interaction are obtained from the location of the 11(x)]11(y) pixellated anodes and the depth (z) is obtained from the ratio of the signals coming from the cathode and the anode. Energy spectra from 662keV incident c-rays have been col...

E!ects of charge sharing in 3-D position sensitive CdZnTe gamma-ray spectrometers

Two 3-D position-sensitive semiconductor c-ray spectrometers operable at room temperature, have been fabricated using 1 cm3 cubic CdZnTe crystals. c-Ray spectra have been obtained from 11(x)]11(y)]20(z) voxels, each corresponding to &0.7]0.7]0.5 mm in the detector volume. Individual spectra from each of the 2420 voxels were corrected for electron trapping, di!erences in weighting potentials, an...

All-electric detection of the polarization state of terahertz laser radiation

Two types of room-temperature detectors of terahertz laser radiation have been developed which allow, in an all-electric manner, the determination of the plane of polarization of linearly polarized radiation and the Stokes parameters of elliptically polarized radiation, respectively. The operation of the detectors is based on photogalvanic effects in semiconductor quantum well structures of low...
