CHFT-40 Hall Thruster with RF Cathode

CFHT-40 Hall Thruster is successfully tested with an in-house built RF cathode inside the BUSTLab Vacuum chamber. The thruster was operated at a discharge voltage of 400 V and a discharge current of 1.2 A with high purity argon gas as the propellant. The RF cathode was run at 50 W RF power using a 13.56 MHz RF power supply. The cathode flow rate was varied between 2 to 5 sccm of argon during the testing.
