提出了一种新的粒子燃料方法的概念，并通过蒙特卡罗模拟研究了其可行性;通过使用紧凑的环面（CT）注入技术和随后的加速CT等离子体的中和，可以产生超高速中性粒子流。当中性气体浓度超过5 × 10 ~（-2）Pa时，CT等离子体中的离子与中和器中的中性粒子发生电荷交换反应，在1 m长的中和器中有效地中和了CT等离子体。
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 × 10-2torr.
