Abstract

CATCH-1 is the first pathfinder within the Chasing All Transients Constellation Hunters (CATCH) space mission. Its payloads include the Silicon Drift Detector (SDD) system and light-weight X-ray optics. The main goal of CATCH-1 is to validate key technologies of the timing satellites in the constellation, such as the electronics of the SDD detector system, Micro-Pore Optics (MPO), and the deployable mast. The SDD detector system is required to operate with high energy resolution and dead time to detect various transients. This paper presents the design and performance of the SDD electronics system of CATCH-1. The electronics system comprises front-end electronics (FEE) and a data acquisition system (DAQ). Test results demonstrate that the energy resolution of all four detector channels are better than 150 eV at 5.9 keV, with the energy band ranging from 0.5 to 8 keV, and the dead time is better than

10 μ s

捕捉星座太空任务的第一探路者（CATCH-1）上的读出电子设备

CATCH-1是追逐所有瞬态星座猎人（CATCH）太空任务中的第一个探路者。它的有效载荷包括硅漂移探测器（SDD）系统和轻型x射线光学系统。CATCH-1的主要目标是验证星座授时卫星的关键技术，如SDD探测器系统的电子技术、微孔光学（MPO）和可展开桅杆。SDD检测系统需要具有高能量分辨率和死区时间来检测各种瞬态。本文介绍了CATCH-1的SDD电子系统的设计和性能。电子系统包括前端电子系统（FEE）和数据采集系统（DAQ）。测试结果表明，在5.9 keV下，4个探测器通道的能量分辨率均优于150 eV，能量带范围在0.5 ~ 8 keV之间，死区时间优于10μs，满足设计要求。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
