我们正在开发一种新的三维蒙特卡罗传输代码“IMPGYRO”，用于分析聚变边缘等离子体中的重杂质。该代码目录求解了测试杂质离子的三维运动方程，以考虑其陀螺运动。大多数重要的过程，如多步电离过程和库仑散射等，也包括在模型中。钨离子快速再沉积速率的计算结果与分析结果吻合较好。此外，在一个简单的平板几何中，对于给定的典型分离等离子体状态的背景等离子体分布，计算了钨离子在每个电荷状态下的二维密度分布。虽然该代码目前仍在开发中，但这些初步结果表明，该代码具有作为一种有用工具的潜力，不仅可以用于分析非常靠近壁面的快速再沉积，而且可以用于分析更大规模的杂质输运过程。
We are developing a new 3D Monte Carlo transport code ‘IMPGYRO’ for the analysis of the heavy impurities in fusion edge plasmas. The code directory solves the 3D equations of motion for the test impurity ions to take into account their gyro motion. Most of the important processes, such as the multi-step ionization process and Coulomb scattering, etc., are also included in the model. The results for the prompt redeposition rate of tungsten ions agree well with the analytic results. In addition, 2D density profiles for tungsten ions of each charge state in a simple slab geometry have been calculated for given background plasma profiles typical of a detached plasma state. Although the code is now still under development, these initial results show that the code has potential as a useful tool, not only for the analysis of the prompt redeposition very close to the wall, but also for the analysis of more large scale impurity transport processes.
