【摘要】：随着我国空间探测的不断发展和精细化研究,质谱计在航天活动中起着越来越重要的作用,但空间用质谱计很难从国外进口,为了解决我国空间探测的急需,我们研制了完全自主知识产权的空间小型磁偏转质谱计,2012年11月在我国新技术试验卫星上实现了成功搭载,已经过近两年时间的空间测试,探测出了地球卫星轨道上的气体成分以及卫星放出的气体成分,空间小型磁偏转质谱计的研制成功将为后续质谱计在空间的广泛应用打下坚实的基础。空间小型磁偏转质谱计由物理部分、电控单元、高压电源三部分组成,体积170 mm×165 mm×165 mm,质量4.5 kg,功耗18 W,质量数范围:1~90 u,最小可检离子流10-13A。
[Abstract]:With the continuous development of China's space exploration and meticulous research, mass spectrometry plays an increasingly important role in space activities, but it is difficult to use space mass spectrometer imported from abroad, in order to solve the urgent need of China's space exploration, we developed a small space magnetic deflection mass completely independent intellectual property rights, in November 2012 the new technology test satellite in China achieved successful flight, space has been nearly two years of testing, to detect the gas composition and the earth satellite orbit of the satellite from the gas composition, lay a solid foundation for wide application of the development of small magnetic deflection space mass spectrometer successfully for subsequent mass spectrometer in small space. Magnetic deflection space mass spectrometer by physical, electronic control unit, the high voltage power supply is composed of three parts, the volume of 170 mm * 165 mm * 165 mm, 4.5 kg and 18 W power quality, quality, number range: 1~90 u, minimum detectable Ion flow 10-13A.
