比较精确地模拟计算中性束注入（NBI）托卡马克等离子体的快离子初始分布是采用大规模数值模拟方法研究NBI快离子相关物理问题的首要任务。本文建立了NBI托卡马克等离子体的简化物理模型,采用蒙特卡罗方法自主开发了NBI应用程序。选取ASDEX Upgrade（AUG）托卡马克上切向注入和垂直注入两种情况为计算实例,分别模拟计算出NBI粒子被离子化的初始三维空间位置,并统计得出初始快离子的径向分布、极向角分布、环向角分布和投掷角分布,这些计算结果与国际上相关文献结果一致。

The accurate simulation of the initial distribution of the fast ions from neutral beam injection (NBI) in Tokamak plasma is the primary task of using large scale numerical simulation method to study the NBI fast ion related physics problems. A simplified physical model for NBI Tokamak plasma was established. A NBI application code was developed independently by using Monte Carlo method. Two typical cases of tangential injection and vertical injection in ASDEX Upgrade (AUG) Tokamak were chosen as computational examples. The initial 3D spatial po...
