Hall effect thruster impedance characterization in ground-based vacuum test facilities

HIGHLIGHTS

• What: The authors overcome the challenge of nonlinearity and time-variance of HETs by conducting a small-signal impedance analysis to characterize the effective resistance and reactance of the HET discharge with a novel and versatile impedance measurement diagnostic. The aim in this work is to implement impedance spectroscopy and prove its utility as an alternative method to characterize the dynamic behavior of a HET. Specifically, the authors aim to quantify resistive, capacitive, inductive, and resonant features contained in the impedance signature of a 7-kW HET between 100 Hz and 300 kHz frequency band.
