Moving plasma in an electric shock tube with pulsed gas injection
The nature of the pulsed plasma produced in a small-diameter electric-shock tube is studied experimentally. The tubes are filled with argon or an argon--nitrogen mixture at 1 torr. An electrodynamic valve is used for pulsed injection of another gas so that a slowly moving interface arises between the main gas and this auxiliary gas. This moving interface is used to produce various operating conditions in the tube. Selected regions of the tube can be filled in different ways (for example, the expansion and discharge regions). A pulsed monopole mass spectrometer shows that moving fronts corresponding to the various ions form in the tube in addition to the luminous front. The propagation and intensity of these fronts are studied. The results suggest that ionizing blast waves are generated; behind these waves there is observed a pulsed flow of a shock-produced plasma without any impurity due to the gas discharge.
