论文摘要
诸如费米大面积望远镜之类的空间伽马射线望远镜已经使用单方面硅条检测器来跟踪由高分辨率的原代伽玛射线产生的次级带电颗粒。在KEV -MEV望远镜靶向的较低能量下，事件重建需要单个检测器中的二维位置信息，尤其是在康普顿制度中。这项工作描述了整体CMOS活性像素硅传感器-Astropix的开发是一种新型技术，可用于未来的伽马射线望远镜。基于旨在在大型强子对撞机的Atlas检测器中使用的传感器（Atlaspix），Astropix有可能保持高性能，同时减少低功耗。这是通过每个CMOS像素中的双重检测和读数功能来实现的。将介绍Astropix开发和测试的状态，以及未来测试和应用的前景。
Space-based gamma-ray telescopes such as the Fermi Large Area Telescope have used single sided silicon strip detectors to track secondary charged particles produced by primary gamma-rays with high resolution. At the lower energies targeted by keV-MeV telescopes, two dimensional position information within a single detector is required for event reconstruction - especially in the Compton regime. This work describes the development of monolithic CMOS active pixel silicon sensors - AstroPix - as a novel technology for use in future gamma-ray telescopes. Based upon sensors (ATLASPix) designed for use in the ATLAS detector at the Large Hadron Collider, AstroPix has the potential to maintain high performance while reducing noise with low power consumption. This is achieved with the dual detection and readout capabilities in each CMOS pixel. The status of AstroPix development and testing, as well as outlook for future testing and application, will be presented.
