【摘要】：嫦娥二号卫星是我国继嫦娥一号卫星成功发射后的第2颗探月卫星,其上搭载的伽玛射线谱仪(Gamma-Ray Spectrometer,GRS)的主要科学目标是探测月表O、Si、Fe、Ti、U、Th、K、Mg、Al、Ca等主量元素.相比嫦娥一号伽玛射线谱仪,嫦娥二号的能量分辨率和探测效率都大大提高.描述了嫦娥二号伽玛射线谱仪的设计和性能测试结果以及在轨飞行的初步探测成果.
[Abstract]:The Chang 'e-2 satellite is the second lunar probe satellite in China following the successful launch of the Chang 'e-1 satellite. The main scientific objective of the Gamma-Ray spectrometer (Gamma-Ray Spectrometerus GRSs) carried on the satellite is to detect the major elements such as the main elements, such as the OSi-Fei-FeSi-Ti-Ti-Ti-Ti-Ti-U Tu, Ki, Mg-K, Al-Ca, etc. Compared with the Chang 'e-1 Gamma ray spectrometer, the Chang'e 1 gamma ray spectrometer, The energy resolution and detection efficiency of Chang 'e-2 are greatly improved. The design and performance test results of Chang'e 2 gamma-ray spectrometer and the preliminary detection results of in-orbit flight are described.
