“…The space testing instruments are expensive and non-reusable, which is difficult to accurately research many microphysical processes. Because of that the laboratory plasma has the characteristics of easily repetition, accurate diagnosis, and low cost [1][2][3] , it's a new method and a development trend that using laboratory plasma to simulate space physical processes [4][5][6][7] . The large proximity space plasma vacuum environment imitation system is an important part of the national major science and technology infrastructure "space environment ground simulation device (SESRI)", it's the main part of the space plasma environment simulation and research system.…”

The operation reliability of spacecraft in orbitis affected by the interaction with space plasma, research on the space enviroment by advanced testing method is important. It is costly to carry out research and analysis with space flight. Therefore, tests using ground vacuum environment simulation system are of significance. This paper proposed the structure design, simulation analysis and numerical calculation methods for the three subsystems of plasma environment simulation system, including vacuum vessel, vacuum acquisition and vacuum measurement and control. The simulation results show that the maximum stress of the vacuum vessel is 113.2MPa , and the maximum deformation is 0.59mm , at the same time, vacuum technology index, structural stability and human-machine interaction performance of the system can meet the experimental research requirement.

“…Parks et al 7 suggest that enhanced electron emission occurs from a containment layer, not identified * on the solar cell interconnectors. It is questionable if such a thick contaminant layer can survive repetitive arc discharges or primary ion collision; 5 In previous work, the author carried out a ground experiment 10 that simulated ion collection by the HVSA from the ionospheric plasma and was modeled using a similarity law. The experiment determined the characteristics of the parasitic current, ion-induced drag, and material degradation by sputtering.…”

A high-voltage solar array, which can generate and transmit electrical power efficiently, may suffer serious degradation from arc discharges on negatively biased portions of the solar array. A qualitative experiment using heat-proof materials, which are different from those commonly used on solar cells, was conducted under conditions that eliminated the chamber wall effects. The experiment showed that there was a dependence of the discharge on the substratum temperature, which implies that surface adsorption of residual gas plays an important role in the initiation of the arc discharge.
