| 摘 要： | 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。

| Abstract: | A one-dimensional neutral transport code including edge molecular processes and wall interaction has been used to simulate low pressure puffing process in the HL-1 edge plasma 8cm in thickness.Neutral hydrogen ionization rate profile, steady-state neutral hydrogen density profile neutral hydrogen particle and energy fluxes both entering the main plasma and heading back to the wall are obtained. In comparison with the case where the neutrals puffed into edge plasma are treated,as atoms, it is found that molecular processes hare a strong effect on the neutral transport in edge region.Some results are supported by experiments. |
