在过去的四年里，我们一直在开发成像碲锌镉像素探测器，优化了用于天体物理聚焦的硬X射线望远镜。这种应用需要中等面积(大约2厘米×2厘米)、相对较小(大约小于500微米)像素和亚keV能量分辨率的传感器。对于在卫星轨道上运行的实验，也需要大约1-2keV的低能量阈值。在这篇文章中，我们描述了所需的探测器性能特征，并报告了我们的开发工作的状况。特别是，我们展示了一个带有定制低噪声超大规模集成电路读取器的原型传感器的结果，该读取器设计用于在2-100kev频段实现优异的光谱分辨率和良好的成像性能
Over the last four years we have been developing imaging Cadmium Zinc Telluride pixel detectors optimized for astrophysical focusing hard X-ray telescopes. This application requires sensors with modest area (approximately 2 cm X 2 cm), relatively small (approximately less than 500 micrometer) pixels and sub-keV energy resolution. For experiments operating in satellite orbits, low energy thresholds of approximately 1 - 2 keV are also desirable. In this paper we describe the desired detector performance characteristics, and report on the status of our development effort. In particular, we present results from a prototype sensor with a custom low- noise VLSI readout designed to achieve excellent spectral resolution and good imaging performance in the 2 - 100 keV band
