One of the objectives of the PASP experiment is the verification of cost-effective ground simulations of high-voltage solar array/space environment interactions by comparison to the flight data. These ground tests consist of electrical characterization, thermal cycling, and plasma chamber simulations. Results of the latter tests are the subject of this paper. Five array modules which are representative of the flight arrays were tested. The module types are planar silicon, planar gallium arsenide, planar silicon passivated with an integrally deposited cover glass, mini-Cassegrainian concentrator, and SLATS concentrator. The modules were biased to -1000 V in varying plasma densities from 4 x 103 to 2 x 105 e/cm3 to provide a data base for comparison to actual flight data. Each array was tested in both dark and illuminated conditions with a load resistance. In addition to monitoring arcing during the plasma tests, the arrays were visually inspected and electrically characterized before and after exposure in the chamber.
