Stationary Plasma thrusters are currently being considered for application to stationkeeping, repositioning and eventually orbit transfer on European spacecraft. For North/South stationkeeping application, the plume of the thruster can interact with spacecraft surfaces such as solar panels. This interaction corresponds to an impingement of high energy xenon ions (300eV) which induces erosion of the impacted surfaces. The erosion products will be a source of contamination for other parts of the satellite which can play a non negligible role in the ageing of the surfaces, particularly on thermal control surfaces. The aim of this paper is to describe the system built by ONERA to evaluate material erosion by Xenon ions and to characterise contamination induced by sputtered particles.
