Using a multi-fluid transport code TASK/TX developed by the representative of this research, plasma rotation driven by the torque arising from charge separation of fast neutrals in tokamaks has been studied and the physical mechanism of this torque was clarified. It is the first time to show the dependence of the efficiency of rotation drive on the vertical angle of a neutral beam injection. We have developed a diffusive transport model of neutrals that influence the formation of plasma density and rotation profiles. A benchmark with a Monte Carlo code verified that the model well reproduced the behavior of neutrals in a core region.

利用本研究代表开发的多流体输运程序ASK/TX，研究了托克马克装置中快中性粒子电荷分离产生的扭矩驱动的等离子体旋转，并阐明了该扭矩的物理机制。这是第一次显示的旋转驱动效率的中性束注入的垂直角的依赖关系。我们已经开发了一个中性粒子的扩散输运模型，影响等离子体密度和旋转配置文件的形成。一个基准与蒙特卡罗代码验证，该模型很好地再现了在核心区域的中性粒子的行为。
