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。
As China’s space exploration continues to develop and refinement of research, mass spectrometry plays an increasingly important role in space activities, but space with mass spectrometer is difficult to import from abroad, in order to solve the urgent need of space exploration in China, we developed Fully independent intellectual property space small magnetic deflection mass spectrometer, in November 2012 in China’s new technology test satellite successfully equipped with, has been nearly two years of space testing, detected the Earth’s satellite orbit gas composition and satellite The successful development of the gas composition and space miniature magnetic deflection mass spectrometer will lay a solid foundation for the subsequent wide application of mass spectrometry in space. The space magnetic miniature magnetic deflection mass spectrometer is composed of three parts: physical part, electronic control unit and high voltage power supply. The volume is 170 mm × 165 mm × 165 mm, the mass is 4.5 kg, the power consumption is 18 W, the mass range is from 1 to 90 u, Ion-inspected flow 10-13A.
