本文通过测量研究了像素化CZT/CdTe探测器的电荷共享和电荷损失效应。我们测量了大量CZT和CdTe像素探测器样品的电荷共享效应函数(相同像素间距)、光子能量和探测器偏置电压。这些结果用于为国际空间站欧空局哥伦布舱计划的大气-空间相互作用监测器(ASIM)开发大面积X射线和伽马射线探测器。在相同尺寸和不同像素间距的探测器样品上进行的电荷共享测量表明，间隙表面的电荷损失与间隙大小成线性关系。
In this paper, charge sharing and charge loss effects in pixilated CZT/CdTe detectors are investigated by measurements. We measured charge sharing effects function of the inter-pixel gap (with same pixel pitch), the photon energy and the detector bias voltage for a large numbers of CZT and CdTe pixel detector samples. The results are used for the development of the large area X-ray and gamma ray detector for the Atmosphere-Space Interactions Monitor (ASIM) planned for the ISS ESA Columbus module. Charge sharing measurements on detector samples with identical size and pixel geometry with different inter-pixel gap showed charge loss on the gap surface which is linear dependent on gap size.
