Abstract :
Studies have been performed to determine the feasibility of D-3He burning in dense plasma focus (DPF) device as a possible propulsion system for space. A large potential difference between the DPF electrodes ionizes the gaseous fusion fuel and forms on annular plasma sheath. The “run-down” phase and the subsequent stability are analyzed by solving the momentum equation using the snowplow model and the cylindrical m=0 mode. It is found that the results of the pinch equilibrium profiles agree with the assumed current-squared scaling of energy density, and that the total fusion power released from the pinch scales as plasma current, Ip 5.4. This is found to correlate well with the reaction rate parameter data for the utilized fuel of D-3He
