    Abstract
  • A technique for rapidly removing the surface contamination from in orbit Langmuir probe is presented. As an important technique for in-suit detection of the space plasma, the Langmuir probe has been widely used in a variety of spacecrafts. When surface of the probe sensor is contaminated, deviation of the Langmuir probe's I-V characteristics curve will be caused, which then results in the plasma parameters' inaccuracy by the detection. In this paper, it has been proved by tests that loading the probe sensor with high voltage can remove the sensor surface contaminants quickly and effectively, which can ensure the real-time accurate space plasma parameters detection by Langmuir probe in orbit.
