Abstract
A pulsed high pressure, supersonic plasma jet for accelerating a projectile through an elongated confined bore is derived from a dielectric structure including a capillary passage having an interior wall surface from which plasma forming material is ablated in response to a discharge voltage applied to first and second electrodes respectively forming a nozzle and plug at opposite ends of the passage. The nozzle injects the plasma into the bore behind the projectile.
