PPS® 1350-G qualification status 10500 h

The PPS® 1350-G Hall Effect Thruster qualification process was continued to achieve 10500 h and 7300 cycles. This paper summarizes the obtained results and main observations for this rare end of life thruster. After a quick overlook of the 2002-2007 steps, it presents all along the lifetime the following parameters and their evolutions: thrust, flow rate, specific impulse, discharge current, discharge current oscillations, efficiency, erosion pattern, cathode parameters. The first end of life expertise will also be discussed. The success of this lifetime qualification at 3.3 10^6 Ns opens new spacecraft propulsion opportunities for high ΔV missions.
