托卡马克聚变试验堆 (TFTR) 中氢速度的蒙特卡罗中性输运模拟 [K. M. McGuire 等人,物理学。 Plasmas 2, 2176 (1995)] 与使用多普勒展宽 Balmer-α 谱线轮廓的实验进行了比较。在一系列条件下获得了良好的一致性,验证了中性气体代码 DEGAS 中电荷交换、分子解离、表面反射和溅射的处理[D. Heifetz 等人,J. Comput。物理。 46, 309 (1982)]。大多数模拟中 10-100 eV 中性粒子的残余缺陷表明,需要进一步研究电子能量超过 100 eV 时 H+2 解离的能量学。
Monte Carlo neutral transport simulations of hydrogen velocities in the Tokamak Fusion Test Reactor (TFTR) [K. M. McGuire et al., Phys. Plasmas 2, 2176 (1995)] are compared with experiment using the Doppler‐broadened Balmer‐α spectral line profile. Good agreement is obtained under a range of conditions, validating the treatment of charge exchange, molecular dissociation, surface reflection, and sputtering in the neutral gas code DEGAS [D. Heifetz et al., J. Comput. Phys. 46, 309 (1982)]. A residual deficiency of 10–100 eV neutrals in most of the simulations indicates that further study of the energetics of H+2 dissociation for electron energies in excess of 100 eV is needed.
