Ion Thruster Performance Impacts due to Cathode Wear

It has been observed in ion thruster wear tests that the discharge loss increases with time and that the thruster performance correspondingly degrades. This behavior is usually attributed to an enlargement of the accelerator grid apertures during the tests due to ion erosion, which increases the gri...
