AI 中文摘要
下一代X射线天文台需要快速、低噪声、低功耗的多百万像素成像光谱仪。为满足这些需求,斯坦福大学的X射线天文学与观测宇宙学(XOC)小组与MIT Kavli研究所、MIT林肯实验室(MIT-LL)合作,正在开发多通道X射线电荷耦合器件(CCDs)和快速读出架构。我们报告了为先进X射线成像卫星(AXIS)概念开发的全尺寸(1440×1440像素)、16通道、正面照射的MIT-LL CCD探测器CCID-100,采用斯坦福大学新CCID-100测试装置中的两块多通道读出芯片(MCRC)V1专用集成电路(ASIC)读出所实现的能量分辨率和噪声性能。我们描述了针对每个CCD通道的自动化偏置优化方法,以及前端ASIC和读出系统的集成调试功能。已验证的性能确认这些系统可满足未来战略X射线任务的速度和噪声要求。
英文摘要
Next generation X-ray observatories require fast, low-noise, low-power, multi-megapixel imaging spectrometers. To meet these demands, the X-ray Astronomy and Observational Cosmology (XOC) Group at Stanford, in partnership with the MIT Kavli Institute and MIT Lincoln Laboratory (MIT-LL), is developing multi-channel X-ray charge-coupled devices (CCDs) and fast readout architectures. We report the energy resolution and noise performance achieved with a full-scale (1440x1440-pixel), 16-channel, front-illuminated MIT-LL CCD detector developed for the Advanced X-ray Imaging Satellite (AXIS) concept, the CCID-100, read out using two Multi-Channel Readout Chip (MCRC) V1 application-specific integrated circuit (ASIC) chips in the new Stanford CCID-100 test setup. We describe an automated method for bias optimization on each CCD channel, and integrated debugging features of the front-end ASIC and readout system. The demonstrated performance confirms that these systems can meet the speed and noise requirements of future strategic X-ray missions.
