The two-dimensional relativistic Fokker-Planck code has been newly developed and combined with the ray-tracing code for analyzing the lower hybrid current drive (LHCD) in Tokamak plasmas. The current drive efficiency evaluated using the parameter of reactor-grade plasmas is about a factor of 1.7-2 times higher than the results obtained from two other analyses (the one-dimensional relativistic Fokker-Planck code combined with the ray-tracing code and the two-dimensional non-relativistic Fokker-Planck code combined with the ray-tracing code). Since the LHCD efficiency enhancement due to the two-dimensional effect and the relativistic effect tends to increase in a high temperature plasma, these effects are important to analyze the lower hybrid current drive in future large Tokamaks.
二维相对论性福克-普朗克代码已被新开发，并与射线追踪代码相结合，用于分析托卡马克等离子体中的低杂波电流驱动（LHCD）。使用反应堆级等离子体参数评估的电流驱动效率，比从另外两种分析（一维相对论性福克-普朗克代码结合射线追踪代码，以及二维非相对论性福克-普朗克代码结合射线追踪代码）所获得的结果高出约1.7至2倍。由于二维效应和相对论效应引起的低杂波电流驱动效率增强在高温等离子体中趋于增加，这些效应对未来大型托卡马克中低杂波电流驱动的分析具有重要意义。
