Abstract:
In order to obtain the parameters of plasma at thruster nozzle center position through the Langmuir probe diagnostic method, and avoid the probe staying at the spout for long time and being burned by plasma, a precise positioning and rapid reciprocating motion diagnostic system was developed by aid of LabVIEW. The system can make the probe arrive at the outlet of Hall thruster rapidly, fulfill current and voltage data acquisition in very short time, and then return to its starting location rapidly and avoid burning the probe. Compared to the data collected by conventional Langmuir probe, the data got by this system can reflect the true state of the plasma
