  • 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 closemore » 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.« less

  • The scientific objectives and future requirements of high energy X-ray astronomy are discussed and concepts for imaging instruments based on CdZnTe detectors and coded masks are reviewed. An instrument concept based on CdZnTe strip detectors, HEXIS, is described in detail. Technical requirements for large area CdZnTe strip detectors are discussed and recent work at UCSD and WU on the capabilities of CdZnTe strip detectors is described in detail. Studies with small, {approximately}50 micron, beams demonstrate that crossed strip detectors have good properties for both spatial and spectral measurements.
