Abstract:

A comparison of the theoretical performance of reverse-feed and porous-tungsten cesium ion engines is made considering 1 power efficiency, 2 propellant utilization efficiency, 3 current densities, 4 emitter temperature, and 5 charge exchange, at specific-impulse levels of 3000 to 10,000 seconds.
