- 論文の詳細を見る
Neutral transport in the TRIAM-1M tokamak was analyzed using Monte Carlo simulation code (DEGAS). In the cases of low-density (${\sim}2\times 10^{12}$ cm-3) and high-density (${\sim}2\times 10^{13}$ cm-3) plasma discharges, the Hα intensity is localized around a neutral source, and in the toroidal direction, the 1/e decay lengths of the Hα intensity in two kinds of discharge differ by a factor of 1.5 to 2. By using a cylindrical mesh model for the DEGAS code, the simulated Hα intensities properly explained the experimental results. A detailed analysis of the simulation results revealed that the Hα profile is significantly affected by the geometric structure of the plasma facing component and the parameters of plasma and neutral particles.
