Current Sheet Tilt in a Radial Magnetic Shock Tube

摘要

This paper describes an experiment carried out in a radial (inverse pinch) shock tube with argon of 50 - 400 micron pressure and hydrogen of 100 micron pressure. The current sheet was found to be tilted so that the cathode side lagged the anode side. At the anode the shock has a tilt in the same direction as the current sheet. At the cathode the shock is normal. These phenomena can be correlated by physical models which assume that the current is predominantly carried by the ions. (Author)
