摘要

The paper deals with the results of two test campaigns carried out at Alta and at Giessen University respectively on Snecma's PPS1350-TSD Hall thruster and on RIT-10 ion engine for performance characterization with nitrogen and oxygen as propellants. The activity sponsored by the European Space Agency is of particular interest for RAM-EP concept. Both thrusters have operated in stable mode with both propellants, although as expected a degradation of performance has been observed, mainly due to the low ionization efficiency.
