摘　　要：通过采用AP8MAX和AE8MAX辐射带质子和电子模式,开展了对我国硬X射线调制望远镜(hard X-ray modulation telescope, HXMT)运行轨道的空间辐射环境分析研究,提出了在该轨道开展空间辐射环境监测的科学目标。通过在配置新一代空间辐射环境监测载荷-空间多向粒子探测器,实现了轨道16个方向180°空间的高能电子和质子的测量,能量范围覆盖了1.5~200 MeV的质子和0.2~1.5 MeV的电子,为确保HXMT科学目标的实现及空间辐射环境的探测研究提供了数据支撑。The hard X-ray modulation telescope(HXMT)is the first space science experiment project dedicated to astronomical exploration in China,which mainly realizes the wide band X-ray(1~250 keV)imaging sky survey.By using the proton and electron modes of AP8MAX and AE8MAX radiation belts,the analysis and research on the space radiation environment of the operating orbit of HXMT satellite are carried out,and the scientific objective of monitoring the space radiation environment in this orbit is proposed.By deploying a new generation of space radiation environment monitoring payload(space multidirectional particle detector)on the HXMT satellite,the measurement of high-energy electrons and protons in 16 directions in 180°space of HXMT satellite’s orbit has been achieved.The energy range covers from 1.5~200 MeV protons and 0.2~1.5 MeV electrons.The payload can provide data support for the realization of the scientific objectives of the HXMT satellite and the detection and research of the space radiation environment.
