| 摘 要： | 先进天基太阳天文台(ASO-S)是中国科学院空间科学先导专项2期规划的太阳观测卫星,其针对第25个太阳活动峰年,同时观测太阳磁场、日冕物质抛射和太阳耀斑爆发.硬X射线成像仪(HXI)作为该卫星3个科学载荷之一,实现了高时间分辨率和空间分辨率的太阳硬X射线成像观测,其量能器由99套溴化镧闪烁晶体-光电倍增管探测单元和读出电子学板构成,实现了30–200 keV的硬X射线光子能谱测量.针对HXI量能器的观测需求,设计了一套空间高事例率读出电子学系统,并通过实验室测试,证明了该系统单事例读出死时间小于2μs,同时验证了该系统电子学噪声小于120 fC,积分非线性小于2%,满足HXI仪器要求.

| Abstract: | The Advanced Space-based Solar Observatory (ASO-S) is the first Chinese solar mission of Chinese Academy of Science, aimed at the 25th solar maximum. ASO-S is expected to observe solar magnetic field, coronal mass ejections (CMEs), and solar flares at the same time. Hard X-ray Imager (HXI) is one of the 3 payloads on board of ASO-S, providing solar X-ray image with high resolution in both time and position. The calorimeter in HXI consists of 99 \ce{LaBr3 |
