An advanced Watt class Hall Micro Thruster (HMT) is offered for Space Gravitational Wave Detection (SGWD), and an investigation has been conducted on its start-up, shutdown, rise, fall response times. The research involved creating a circuit thruster discharge signal acquisition, using Faraday probe to measure the plasma plume generated by thruster, characterizing thrust directly. Ultimately time of extracted from current signals. experimental results demonstrate that HMT ranging 1.08 ms 16.76 at mass flow rates 0.02 mg/s 0.04 mg/s, meeting SGWD requirements micro time. This provides physical foundation explanation variation with voltage versus rate several key parameters affect discharge, such as neutral gas number density (nn) ionization mean free path (λi). Furthermore, we have examined anomalies in signal. Overall, this brand-new method measuring electric thrusters.
