质谱仪在深空探测中的应用

深空探测是对太阳系、银河系乃至宇宙空间的探测活动。质谱仪在深空探测活动中起着重要的作用。本研究首先介绍了各国探测器的探测任务，以及有效载荷中质谱仪的质量、体积、功耗、质量探测范围和分辨率等主要参数；然后，进一步分析了每种质谱仪的离子源类型、质量分析器类型和针对特殊任务做的改进；最后，通过比较各种类型质谱仪的性能，对质谱仪在今后深空探测任务中的应用前景进行了展望。

Application of Mass Spectrometer in Deep-Space Exploration

Deep-space exploration is exploration activity of the solar system, the galaxy system and the space. Mass spectrometer plays an important role in deep-space exploration activities. Firstly, besides the mission of the probe in different countries, the main parameters of the mass spectrometer in the payload, like mass, volume, power, mass range and mass resolution were introduced. Then the ion sources, mass analyzers of every type of the mass spectrometer and also the improvements for the special missions were analyzed. Finally, through comparing with the performance of different types of mass spectrometers, the prospect of mass spectrometers applied in future deep spaceexploration was discussed.
