【 摘 要 】

The project objectives are: (1) determine for the first time the properties limiting the performance of CZT detectors; (2) develop efficient, non-destructive techniques to measure the quality of detector materials; and (3) provide rapid feedback to crystal growers and, in conjunction with suppliers, improve CZT detector performance as measured by device energy resolution, efficiency, stability and cost. The goal is a stable commercial supply of low-cost, high energy resolution (0.5% FWHM at 662 keV) CZT crystals for detecting, characterizing and imaging nuclear and radiological materials in a wide variety of field conditions.
