Description

technical field [0001] The invention belongs to the technical field of space environment simulation, in particular to an electron accelerator device used for simulation of the charging environment on the surface of the moon. Background technique [0002] The moon is the only natural satellite of the earth. Lunar exploration has always been a hot topic in China's aerospace industry. However, the extremely harsh environment of the moon's surface, such as vacuum, high and low temperature, and charged dust, poses a threat to lunar-based equipment (including landers, rovers, robots, and detectors). etc.) and astronauts on the moon are a major test, especially the charged moon dust. Under the action of the approximate vacuum of the moon, huge temperature difference, solar wind, ultraviolet radiation, and electron radiation, the fine moon dust is easy to carry Electric charge. Due to the high vacuum environment of the Moon, particles of lunar dust can remain charged for long period...
