PROJECT TITLE : New Technology Plasma Contactor

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

A new technology plasma contactor is proposed for charge control of large satellites and space structures, using higher voltage solar arrays, to enable these spacecraft to operate reliably in a wide range of ambient space plasma environments. A unique plasma source design is presented which is capable of operating over a wide range of plasma electron currents, including transient, very high current spacecraft discharging demands, while requiring a minimum gas flow and very low power. Specific source design and operational tests are described for Phase I proof-of-concept demonstration of this new, scalable plasma contactor technology.
POTENTIAL COMMERCIAL APPLICATIONS
Commercial benefits of the proposed technology development path would be the availability of a versatile charge control system, adaptable to a wide range of future spacecraft charge control requirements.
