Abstract :
A new concept of particle fueling method is proposed, and its feasibility is studied by a Monte Carlo simulation; by using a compact torus (CT) injection technique and subsequent neutralization of an accelerated CT plasma, ultrahigh-speed neutral-particle flow can be generated. The charge-exchange reaction between ions in a CT plasma and neutral particles in the neutralizer is found to work efficiently to neutralize the CT plasma within a 1-m long neutralizer in a case that the neutral gas exceeds 5 × 10-2 torr.
