高能聚变产物与燃料粒子间的rn核加库仑相干散射

摘要

在具有较高电子温度的D-３He聚变等离子体中，强子弹性散射、核加库仑相干散射和核反应产物的传播等效应变得相对重要，而聚变产生的高能离子与电子的库仑相互作用变弱。部分本底燃料离子被聚变产生的高能离子轰击而成为麦克斯韦分布函数尾部的“超热”燃料离子，从而提高了D-３He聚变反应。%Some effects such as hadronic elastic scattering,nuclear plus Coulomb interference scattering and propagation of fusion products become pronounced in D-３He fusion plasma with high temperature while Coulomb interactions of energetic ions produced by fusion reaction and plasma electrons get weaker.A fraction of background fuel ions due to the knock of fusion products becomes superheat tail ions in the Maxwellian distribution,therefore D-３He fusion reaction is enhanced.
