High-energy characterization of two large-volume multi-element CdZnTe detectors

PDF Version Also Available for Download.

Description

We present results of experiments to characterize two large-volume, multi-element CdZnTe detectors for gamma-ray spectroscopy at high energy. The first detector consisted of four 1.5 cm x 1.5 cm x 0.75 cm coplanar grid detectors. The measurements for the four-element design were performed with various configurations. The second detector consisted of eight 1 cm x 1 cm x 0.5 cm coplanar grid detectors arranged in a 2 x 2 x 2 array. The high-energy gamma-ray sources included {sup 60}Co(1332), {sup 228}Th(2614), {sup 244}Cm/{sup 13}C(6129), and Fe(n,{gamma})(7645). The front-end electronics consisted of eight spectroscopy-grade preamplifiers/shapers/pulse stretchers, built on circuit boards close ... continued below

We present results of experiments to characterize two large-volume, multi-element CdZnTe detectors for gamma-ray spectroscopy at high energy.

The front-end electronics consisted of eight spectroscopy-grade preamplifiers/shapers/pulse stretchers, built on circuit boards close to the arrays. For the four-element measurements the shapers/pulse stretchers were replaced with commercial amplifiers. An eight-channel data acquisition system with list mode output was used to record gamma-ray events for each detector element in each array. The list mode data were analyzed to produce coincidence and singles spectra and efficiencies for the various sources. The Compton continuum and the escape peaks are suppressed in the coincidence spectra relative to the singles spectra. We compare these spectra and efficiencies at high energy to results at lower energies and to Monte Carlo predictions.
