本文对于粒子束聚变研究的进展及当前尚待解决的关键问题作了概括论述。轻离子束是惯性约束聚变潜在的理想的驱动器,因为产生轻离子的脉冲功率源价格较低,产生的效率也高。对于能有效地产生高亮度的离子束二级管的研究作了描述。对轻离子束的阻止本领作了计算,其中包括靶中束缚电子和自由电子的效应。实验结果表明,当束的电流密度比较高时,阻止本领比冷靶时增大2倍。内爆的研究已经开始,做过圆柱的内爆实验。 In this paper, the progress of particle beam fusion research and the key issues to be solved are summarized. Light ion beams are potentially ideal drivers for inertial confinement fusion, as pulsed power sources that generate light ions are less expensive and produce more efficiency. A description of the research on ion beam diodes that can efficiently produce high brightness has been described. The stopping power of light ion beams has been calculated, including the effects of binding electrons and free electrons in the target. Experimental results show that when the beam current density is relatively high, the ability to prevent the increase of 2 times more than the cold target. Implosion of the study has begun, done a cylindrical implosion experiment.
