We report on the impact of anisotropy to tokamak plasma configuration and stability. Our focus is on analysis of the impact of anisotropy on ITER pre-fusion power operation 5~MA, $B=1.8$~T ICRH scenarios. To model ITER scenarios remapping tools are developed to distinguish the impact of pressure anisotropy from the change in magnetic geometry caused by an anisotropy-modified current profile. The remappings iterate the anisotropy-modified current profile to produce the same $q$ profile with matched thermal energy. The analysis is a step toward equilibria that are kinetically self-consistent for a prescribed scenario. We find characteristic detachment of flux surfaces from pressure surfaces, and an outboard (inboard) shift of peak density for $T_{\parallel}>T_\perp$ ( $T_{\parallel}

各向异性对 ITER 情景的影响

我们报告了各向异性对托卡马克等离子体构型和稳定性的影响。我们的重点是分析各向异性对 ITER 预聚变功率运行 5~MA、$B=1.8$~T ICRH 情景的影响。为了对 ITER 情景建模,开发了重新映射工具,以区分压力各向异性的影响与由各向异性修改的电流剖面引起的磁几何变化的影响。重新映射迭代各向异性修改的电流分布以产生具有匹配热能的相同 $q$ 分布。该分析是朝着在规定场景中动力学自洽的平衡迈出的一步。我们发现通量表面与压力表面的特征分离,以及 $T_{\parallel}>T_\perp$ ( $T_{\parallel}
