本文采用新版的一维中性粒子输运程序,在平板几何下模拟了HL-1装置边缘8cm区域的分子过程及中性粒子与壁相互作用对中性粒子输运的影响,得到了电离速率的径向分布、稳态中性氢原子径向分布、壁与边缘等离子体区之间、芯部等离子体与边缘等离子体之间中性氢各种粒子通量、能量通量并与只含原子过程的类似计算进行了比较,结果表明边缘区的分子过程对巾性氢原子输运有显著的影响。有些结果得到实验的证实。
In this paper, the new one-dimensional neutral particle transport program was used to simulate the molecular process in the 8 cm edge of HL-1 device and the effect of neutral particle-wall interaction on the transport of neutral particles under the plate geometry. The ionization rate The radial distribution of steady-state neutral hydrogen atoms, the flux of neutral hydrogen between the core plasma and the edge plasma, the energy flux between the core and the edge plasma, Similar calculations of atomic processes were compared and the results showed that the molecular processes in the marginal zone had a significant effect on the transport of the scarlet hydrogen atoms. Some results have been experimentally confirmed.
