And the control data transmission system respectively controls the X-ray tube assembly and the X-ray measurement system. The device can assist the lunar dust cabin to realize simulation of a lunar surface dust electrification environment and effect, carry out physical theory research on lunar surface dust, and clarify physical processes and rules of lunar dust charging, discharging, dust raising, migration, sedimentation, deposition and the like.

Description

technical field [0001] The invention belongs to the technical field of space environment simulation, and in particular relates to a positive electric environment simulation device which utilizes X-ray irradiation to realize high potential on the lunar surface. Background technique [0002] Under the action of sunlight, solar wind plasma and high-energy particle flow in space, the lunar surface and dust particles will be charged with a certain polarity and intensity of potential. The charged lunar surface dust particles will be suspended to a certain height under the action of electrostatic force, forming a wrapped global three-dimensional distribution that can reach a height of nearly a kilometer. The electrostatic suspended dust migrates under the action of the electric field on the lunar surface, especially in the morning and evening, and can form a moon dust fountain phenomenon. In order to simulate the phenomenon of the moon dust fountain, the moon dust module has estab...
