英文摘要
Whereas electric propulsions perform extremely high specific impulse compared with chemical propulsions, their lifetime performance is critically important because their low thrust. In this study, an experimental erosion measurement method and a numerical lifetime simulation model were developed towards long-life Hall thruster. As a result, real-time erosion visualization method was established by utilizing nano-meter order multilayer coating. Furthermore, plasma-wall interaction was simulated by the developed numerical code and clues toward long-life Hall thruster were obtained.
