【摘要】：嫦娥二號衛(wèi)星是我國繼嫦娥一號衛(wèi)星成功發(fā)射后的第2顆探月衛(wèi)星,其上搭載的伽瑪射線譜儀(Gamma-Ray Spectrometer,GRS)的主要科學(xué)目標(biāo)是探測月表O、Si、Fe、Ti、U、Th、K、Mg、Al、Ca等主量元素.相比嫦娥一號伽瑪射線譜儀,嫦娥二號的能量分辨率和探測效率都大大提高.描述了嫦娥二號伽瑪射線譜儀的設(shè)計和性能測試結(jié)果以及在軌飛行的初步探測成果.
[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.
