Description

technical field [0001] The invention relates to a device for monitoring the charging potential of the deep medium of a spacecraft, which belongs to the field of anti-radiation reinforcement. Background technique [0002] The currently equipped spacecraft deep medium charging monitor directly measures the electron flux that causes the charging of the deep medium, and then judges the charging degree of the spacecraft based on experience, but cannot directly measure the charging potential value of the deep medium. [0003] In view of this, a spacecraft deep medium charging potential monitoring device is proposed, which can monitor the charging potential of the spacecraft internal medium in real time, and the measurement process will not affect the measured potential. Contents of the invention [0004] The purpose of the present invention is to provide a device for monitoring the charging potential of the deep medium of the spacecraft, which can be mounted on the spacecraft fo...
