一个小的像素化的γ射线探测器已被构造从5 mm厚的CdZnTe衬底和其特征在于光谱和空间特性。重点放在揭示“像素级”的结果，以进一步了解最佳的阵列设计和操作。阳极设计为（1.5/spl times/1.5）mm/sup 2/ pixels，间距为1.625 mm。光谱结果与/sup 57/Co源显示的平均能量分辨率为3.9 keV半高宽。对不同像素的电子噪声分析表明，与理论模型吻合良好，边缘和内部像素之间的性能相似。与扫描源入射在阳极面的空间响应的测试显示出良好的协议与像素的几何形状和不可检测的量的相互作用深度的依赖。
A small pixellated gamma-ray detector has been constructed from a 5 mm thick CdZnTe substrate and characterized for spectroscopic and spatial properties. Emphasis has been placed on revealing 'pixel-level' results to further understand optimum array design and operation. The anode design is (1.5/spl times/1.5) mm/sup 2/ pixels on a 1.625 mm pitch. Spectroscopic results with a /sup 57/Co source display an average energy resolution of 3.9 keV FWHM. Analysis of the electronic noise for different pixels showed good agreement with a theoretical model and similar performance between edge and interior pixels. A test of spatial response with scanned sources incident on the anode face showed good agreement with the pixel geometry and an undetectable amount of dependence on interaction depth.
