The xenon feed system (XFS) is designed for storing and supplying the required amount of working substance to the Hall-effect thruster, which ensures its operation with the specified parameters. Based on all possible feed systems analysis, it was chosen a pneumo scheme with accumulator tank and flow restrictors. Pressure in accumulator tank is maintained at a predetermined level with the help of solenoid valves. The characteristics and design of XFS are determined in accordance with the characteristics of the thruster. The XFS structure consists of two subsystems: high pressure unit and low pressure unit. The high pressure unit remains unchanged in propulsion systems with a different number of Hall-effect thrusters and the number of low pressure units varies according to the number of thrusters. XFS includes pressure transducers and temperature sensors to control system conditions.
