Abstract :
A snap of microwave plasmatron operation stability within the pressure range in medium vacuum was developed and tested on the basis of an optical diagnostics technique. The essence of the technique is simultaneous synchronous recording of the signal from the vacuum-gauge analog output and the signal from the photoelectric multiplying tube. Recording is carried out during plasmatron pumpout from the moment of gas cut-off to the moment of discharge starvation. We compared the data obtained during investigation of microwave discharge stability in different modes of plasma generation with the results of the snap of discharge glow properties. Such analysis proves the reliability and high informativity of the developed technique.
