Abstract
A self‐crowbar switch for a gas‐puff z‐pinch, driven by a pulsed power generator with output voltage 600 kV, pulse width 70 ns, and characteristic impedance of 3 Ω, has been built and tested successfully. Discharges with pulsed gas injection are placed into four groups dependent on the delay between the pulsed power generator trigger time and the gas‐puff trigger time. For short delay times (6 ms), a z‐pinch does not occur. The self‐crowbar switch is believed to operate by photoionization of puffed gas which has reached the switch region.Keywords
