Description

technical field [0001] The invention relates to a space low earth orbit plasma environment simulation experiment system, which belongs to the technical field of space application equipment. Background technique [0002] In order to verify the authenticity and reliability of the on-orbit functions and performance indicators of space payloads, it is necessary to conduct experimental verification, calibration, testing and analysis and evaluation of space payloads in the ground plasma environment. [0003] Under normal circumstances, the electron density of space low earth orbit plasma is 10 9 / m 3 ~10 12 / m 3 , The electron temperature is 1000K~5000K. Existing space plasma environment simulation equipment is generally created for plasma environment parameters at different space orbit heights. Due to different experimental purposes, the main parts (vacuum container and ion source) of these plasma environment simulation equipment are also different, with a plasma uniform are...
