Abstract : On September 30, 1993, the Department of Physics at Hampton University was awarded a research instrumentation grant by the AFOSR for the development of an advanced Thermal and Electric Propulsion (TEP) system. Under this grant, a TEP test facility capable of providing 60-kW optical power for thermal propulsion and 30-kW electric power for the magnetoplasmadynamic (MPD) thruster has been constructed and installed. The TEP is literally of thermal and electric propulsion systems in a tandem order to take advantage of both systems. The TEP employs a high temperature thermal chamber for generation of an ionized propullant and a hollow cathode of the MPD as an expansion nozzle. Both feature alleviate the requirement of high voltage triggering and concentration of the current density on the solid cathode tip that commonly appear in the conventional MPD thrusters.
