Abstract—The global characteristics of an ATON stationary plasma thruster operating on xenon and krypton
are investigated. It is shown that, with krypton, the thrust at the same mass flow rate of the working gas is greater
and the efficiency is somewhat lower than those with xenon. An efficiency of ~60% was achieved with krypton
for the specific impulse attaining 3000 s. The jet divergence is ~ 22 for krypton and ~ 11 for xenon. © 2002
