HiZ-GUNDAM宽视场低能X射线成像探测器的研制
Development of wide-field low-energy X-ray imaging detectors for HiZ-GUNDAM
摘要：
我们正在计划未来的伽马射线暴（GRB）任务HiZ-GUNDAM，以探测红移z > 7的早期宇宙。目前，我们正在研制一个小型的宽场低能X射线成像探测器原型，用于观测能量范围为1 - 20 keV的高z伽玛暴。在本文中，我们报告的原型系统和性能的概述，特别是专注于高增益模拟ASIC的特性和辐射耐受性，专门设计用于读出小电荷信号。
英文摘要：
We are planning a future gamma-ray burst (GRB) mission HiZ-GUNDAM to probe the early universe beyond the redshift of z > 7. Now we are developing a small prototype model of wide-field low-energy X-ray imaging detectors to observe high-z GRBs, which cover the energy range of 1 - 20 keV. In this paper, we report overview of its prototype system and performance, especially focusing on the characteristics and radiation tolerance of high gain analog ASIC specifically designed to read out small charge signals.
