| 中文摘要: |
| 针对中国聚变工程试验堆(Chinese fusion engineering test reactor,CFETR)的正常磁剪切平衡位形,采用测试粒子模拟方法,研究了存在磁流体动力学(Magnetohydrodynamics,MHD)低频(2,1)模磁扰动条件下CFETR聚变产物高能α粒子的损失规律。模拟结果表明:在无磁扰动时,α粒子的损失率很低,但在有磁扰动时,α粒子与(2,1)模发生了强烈的相互作用,α粒子的损失率随着(2,1)模磁扰动幅值的增大而显著增大,损失的α粒子的初始位置主要集中在(2,1)模中心位置附近,初始位置分布在靠近磁轴芯部区域的α粒子没有损失,所有损失的α粒子几乎都是从等离子体赤道面以下飞出。 |

| Aiming at the normal magnetic shear equilibrium configuration of China Fusion Engineering Test Reactor (CFETR),the losses of energetic α particles of the fusion products in CFETR under low frequency (2,1) mode magnetic perturbation of magnetohydrodynamics (MHD) were studied by using test particle simulation method.The simulation results show that the loss rate of α particles is very low in the absence of magnetic perturbations,but there is a strong interaction between α particles and (2,1) mode in the presence of magnetic perturbations.The loss rate of alpha particles increases significantly with the increase of (2,1) mode magnetic perturbation amplitude,and the initial position of the lost α particles is mainly concentrated near the (2,1) mode center.These α particles initially located near the core of the magnetic axis have no loss,and almost all the lost α particles fly out from below the plasma equator. |
