The Satellite Positive Ion Beam System SPIBS instrument is being developed as a charge ejection payload for the Air Force Satellite P78-2 Satellite Charging At High Altitude. SPIBS will allow controlled ejection of xenon ions as part of the systematic investigation of satellite charging. Ion Beam currents of about 0.3 and 1.0 mA are obtained at a beam voltage of 1 kV currents of about 0.7, 1.4, and 2.0 mA are obtained at 2 kV. Redundant filament neutralizers are provided to allow full or partial beam neutralization and an independent source of electrons. These neutralizers can be biased at ten levels from -1 kV to 1 kV with respect to satellite ground. This paper describes the engineering model design, and presents ion source, expellant, and power processor test results. Author
