DAMPE飞行任务机载中子探测器的校准和性能
Calibration and performance of the neutron detector onboard of the DAMPE mission
摘要：
2015年12月17日，中国科学院空间科学战略先行计划框架下的四项天基科学任务之一的暗物质粒子探测器（DAMPE）在酒泉发射中心成功发射。DAMPE最重要的科学目标之一是通过测量高能宇宙射线电子的光谱来间接寻找暗物质存在的证据。中子探测器是DAMPE的四个子有效载荷之一，通过测量簇射过程中产生的次级中子来区分高能电子和强子背景。本文介绍了中子探测器的设计、刻度和性能。模拟数据和飞行数据的分析表明，中子探测器具有强大的质子排斥能力，这对DAMPE的TeV电子识别起着至关重要的作用。
英文摘要：
The DArk Matter Particle Explorer (DAMPE), one of the four space-based scientific missions within the framework of the Strategic Pioneer Program on Space Science of the Chinese Academy of Sciences, has been successfully launched on Dec. 17th 2015 from Jiuquan launch center. One of the most important scientific goals of DAMPE is to search for the evidence of dark matter indirectly by measuring the spectrum of high energy cosmic-ray electrons. The neutron detector, one of the four sub-payloads of DAMPE, is designed to distinguish high energy electrons from hadron background by measuring the secondary neutrons produced in the shower. In this paper, a comprehensive introduction of the neutron detector is presented, including the design, the calibration and the performance. The analysis with simulated data and flight data indicates a powerful proton rejection capability of the neutron detector, which plays an essential role for TeV electron identification of DAMPE.
