摘要：

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 (1.5x1.5) mm(2) pixels on a 1.625 mm pitch. Spectroscopic results with a Co-57 source display an average energy resolution of 3.9 keV FHWM. 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 incident radiation scanned across the anode face show good agreement with the pixel geometry and an undetectable amount of dependance on interaction depth.
