Development of Xenon feed system for a 300 W Hall-effect Thruster

A Xenon feed system has been dev eloped for a 300 W Hall-effect thruster intended for orbit maintenance of small satellite. The system can store about 2 kg of xenon gas at 150 bar and is capable of controlling the mass flow rate of the gas at 0.5 SCCM resolution. The performance of t he system is verified with a laboratory experiment. It is confirmed that the operation of the feed system is successfu l at a pressure level of 1.0×10 -6 torr in the vacuum chamber.
