Analysis of an arc-driven railgun for fusion fuel pellet injection

The behavior of an arc-driven railgun for hydrogen pellet injection is examined. Launch of saboted and unsaboted pellets is considered, and the arc mass influence on the behavior of the accelerating system is analyzed in both cases. The characteristic quantities of the hydrogen plasma armature are evaluated by means of an adimensional model. The efficiency of the system is investigated as to whether or not the energy remaining in the railgun at the time of launch is recovered.<
