Abstract

A ground facility was developed for simulation of material and space plasma interaction and for study of spacecraft charging and discharge phenomena. The space plasma simulator consisted of a vacuum tank 0.7m in diameter ×1.5m long, two turbo-molecular pumps with pumping speeds 5 and 3m3/s, respectively, achieving some 10-4Pa, and an electron cyclotron resonance plasma source of a magnetic-field-expansion plasma accelerator. Oxygen or nitrogen plasma properties of plasma density, electron temperature, ion incident energy, ion freestream velocity and atomic oxygen flux were measured. The simulator was found to have a high potential for ground tests.
