摘要
为了估计偏滤器靶板材料的腐蚀速率和寿命 ,应用基于离子输运双群模型的溅射理论计算了聚变带电粒子H+ 、D+ 、T+ 和α粒子轰击Mo、W和Li偏滤器靶板表面的溅射产额 ,并与蒙特卡罗方法的计算结果作了比较。这些数据对估计对等离子体部件的寿命和堆芯等离子体中的杂质水平是有意义的。
In order to estimate the erosion rate and lifetime of divertor target materials,the sputtering yields of Mo,W an Li bombarded by charged particles H +,D +,T + and α are calculated by application of sputtering theory based on bipartition model of ion transport.The comparisons between the results and Monte Carlo calculation ones are made.These data can be used to estimate the lifetime of plasma facing components and analyze the impurity level in core plasma of fusion reactors.
