摘要
本文采用蒙特卡罗杂质输运程序DIVIMP,针对先进实验超导托卡马克(EAST)的上单零位形放电,模拟研究了不同漂移情况下(无漂移、离子B??B漂移向下/上)的钨杂质产生和输运特性。结果表明,经典漂移显著影响了钨杂质自偏滤器靶板的溅射通量及其在上游区域的含量。
In this paper,the Monte-Carlo impurity transport code DIVIMP is used to simulate the tungsten impurity production and transport properties under different drift conditions(no drifts,ion B??B drift directing to the upwards/downwards)for the discharge of the upper single null in the experimental advanced superconducting tokamak(EAST)device.The results show that the classical drifts significantly affect the tungsten impurity sputtering from the divertor target and its content in the upstream.
