A magnetically enhanced Micro-Cathode Vacuum Arc Thruster (µCAT) was designed and fabricated at the George Washington University (GWU). This thesis reports on the results of experimental performance testing of the µCAT. The thruster impulse and exhaust velocity were considered as well as various energy and efficiency values. Magnetic field simulations were conducted of different permanent magnet configurations that could be used in the magnetically enhanced µCAT. Plasma parameters within the µCAT were examined. Finally, a possible µCAT application to perform an orbit change maneuver for a small satellite was considered.
