Abstract

Under conditions of a vacuum simulation it was investigated how electric rocket thruster (ERT) SPT-70 contaminates space craft (SC) surfaces. The contamination content in the ERT jet was studied by using solid targets. The film composition was analysed by Rutherford backscattering spectroscopy (RBS) He+ ions and nuclear reaction analysis (NRA) with H+ ions methods. Using the results of this analysis a preliminary estimation of the composition and the angular distribution of contaminated components in the ERT jet were carried out.
