N2 - A data acquisition and control system has been built in order to test characteristics of Hall effect thrusters. Hall effect thrusters are electromagnetic propulsions devices capable of high thrust efficiencies at specific impulses. Thrusters tested were the D-55, SPT-100, and T-100. The data acquisition and control system was built at Texas Tech, then assembled at NASA Lewis Research Center in Cleveland, Ohio, where all tests were performed. The types of thruster characteristics examined were current oscillations and plasma density fluctuations. The control system consisted of a D/A board, solid state relays, isolation amplifiers, and software. The data acquisition system was comprised of two AID boards, isolation 2 amplifiers, current probes, and sofhvare. Both systems were controlled from a 486/50 MHz computer.
