多杂质输运的影响对偏滤器等离子体的性能有重要影响。为了精确地模拟辐射偏滤器等离子体，我们将集成偏滤器程序SONIC扩展到多杂质组分的模拟。对于音速扩展，开发了一种新的集成建模框架，采用多程序多数据方法和消息传递接口数据交换。在这个框架中，可以用几个蒙特卡罗动力学杂质程序同时处理两个或更多的杂质。用扩展的SONIC程序对JT-60SA辐射偏滤器等离子体进行了分析。包括多杂质输运在内的声速模拟表明，可以实现与稳态高β等离子体相容的辐射偏滤器等离子体场景。
The effects of multi‐impurity transport are important for the divertor plasma performance. To simulate the radiative divertor plasma precisely, we have extended the integrated divertor code, SONIC, to the simulation with multi‐impurity species. For SONIC extension, a new integrated modelling framework using the multiple‐program multiple‐data approach and message passing interface data exchange has been developed. In the framework, two impurities and more can be treated simultaneously with several Monte Carlo kinetic impurity codes. The extended SONIC code has been applied to analyse the JT‐60SA radiative divertor plasma. The SONIC simulation including multi‐impurity transport demonstrates that the radiative divertor plasma scenario compatible with the steady‐state high‐βplasma can be achieved.
