采用高斯光束的研究方法,结合Fokker-Planck方程,在堆级等离子体条件下模拟了发射波功率密度的改变对电子回旋波功率沉积以及电流驱动的影响.结果表明,高功率密度的波束会拓宽功率沉积剖面,使功率沉积的位置略有外移,电流驱动效率略有降低.

In the condition of reactor scale plasma, the influence of incident wave power density on electron cyclotron current drive and power deposition is studied with the relativistic Fokker-Planck equation incorporated into a beam-tracing code. The results show that current drive efficiency is reduced slightly, power deposition profile is broaden and move towards the edge plasma a little, due to the high power density wave beam.
