Abstract

The invention relates to a simulation device of a satellite deep charging and discharging phenomenon. The simulation device includes a particle beam generation device, a vacuum tank, a vacuum maintaining subsystem, a particle detector and a test data subsystem. The particle beam generation device is used for generating high-energy electron beams, wherein the high-energy electron beams irradiate on a test sample; the vacuum tank is used for providing a vacuum chamber space for the simulation device; the vacuum maintaining subsystem is used for maintaining a vacuum environment for the vacuum tank; and the particle detector is used for detecting particle beams to determine whether particle input is normal; and the test data subsystem is used for acquiring data for a simulation test.

Description

technical field [0001] The invention relates to a ground simulation technology for the effect of particle radiation on a satellite, in particular to a simulation device for simulating the charging and discharging of space high-energy electrons in a satellite medium (also known as satellite deep charging and discharging or electrification in a satellite). Background technique [0002] Due to the action of high-energy particles, the medium or ungrounded conductor inside the satellite will form a deep charging of the satellite similar to the electrostatic charging on the ground, that is, the charged particles in space accumulate in the internal medium of the satellite, which will cause the internal medium of the satellite. The accumulation of charge, and the formation of an uneven electric field inside the satellite medium or a large potential difference between the satellite medium and the surrounding space, is called satellite deep charging. When the field strength in the con...
