中文摘要：

介绍了研究的像素CdZnTe探测器的研发情况，包括探测器的制作和性能检测。4×4面阵CdZnTe的尺寸为11 mm×11 mm×6.3 mm，像素为2 mm×2mm。性能最好的一个像素对^137Cs 662keV伽玛射线的能量分辨率达到了1.4%，在加保护环并进行各像素峰位归一修正后，整个CdZnTe探测器对 ^137Cs 662keVγ射线的能量分辨率为2.08%。

英文摘要：

The paper introduced the development of a pixel CdZnTe detector by our research group, including the preparation of the CdZnTe detectors and the performance test. The size of the 4 4 pixel detector is 11 11 6.3mm^3 and the pixel size is 2 2mm^2. The energy resolution of the best pixel for ^137Cs 662keV gamma ray is 1.4 %. After adding a guard ring and the peak position normalization, the total energy resolution is 2.08%.
