Abstract: The plume of the Hall thruster has negative effects on cover glasses of the solar panel which have high light transmission.Therefore, it is necessary to design some protective structures for solar array.Firstly, some related works were reviewed. Then, two different protection schemes were simulated using hybrid-PIC for a GEO satellite equipped with a SPT100. Finally, the advantages and disadvantages of the two schemes were analyzed and some valuable suggestions were proposed. The output power of solar array will be decreased if they are polluted.

Key words: Hall thrusters, SPIS, sputtering, plume simulation, plume shield
