Abstract
The plasma diagnosis technology is an essential tool to investigate the plasma characteristics in the pulsed plasma thruster, which can understand the fundamental mechanisms behind pulsed plasma thruster. This review introduces the application of plasma diagnostic technology in pulsed plasma thrusters, investigates the research status of plasma diagnostic technology applied to pulsed plasma thrusters, and discusses usual plasma diagnostics methods. In the contact diagnosis method, the application of Langmuir three probes in the plasma diagnosis of the pulsed plasma thruster is mainly introduced. In the non-contact diagnosis method, the application of optical emission spectroscopy in plasma diagnosis in pulsed plasma thruster is mainly introduced. The advantages and disadvantages of Langmuir three probes and optical emission spectroscopy in plasma diagnosis are analysed.
