Abstract
A fast, arc‐driven hydrogen gas source and its application as a module in a scheme for multiple downstream propellant supply to a light‐gas gun is described. The potential of this scheme for high‐speed acceleration of hydrogen fuel‐pellets for fusion plasma fueling is considered. In experiments with a single module in which 200 J of electrical energy were dissipated with a power level approaching 5 MW within 30 μs, the velocity of a 23‐mg plastic dummy pellet was increased from 1.7 to 2.4 km/s.
Barrel pressure transients and arc characteristics are described.
