Compatibility issues associated with using field emission array (FEA) cathodes as the electron sources for Hall and ion thrusters were explored and FEA cathode performance is discussed. The cathode environment was characterized using a Faraday probe and NPF probe to determine the local neutral particle pressure and ion flux. A model was used to study the effects of gate voltage, local pressure, and cathode material on cathode lifetime. A sheath model was developed to determine field emission current limitations from a FEA cathode into a virtual anode. Performance comparisons are made between silicon and molybdenum cathodes.
