Abstract: Plasma cathodes for micro Hall and ion thrusters of unprecedented power efficiency, low cost, compactness, are provided. The cathodes employ, for example, a very small planar scandate cathode as electron source, delivering over 350 ma of discharge from an emitter area as small as only 0.012 cm2.
