射频波电流驱动抑制双撕裂模不稳定性研究
Numerical Study on Suppression of Radio Frequency Wave Current Drive on Double Tearing Modes Instability
摘要
Abstract
Controlling double tearing modes instability by radio frequency (RF) wave current drive was explored by using numerical simulation with incompressible magnetohydrodynamics (MHD) in a periodic cylinder.The results show that a localized driven current along the background current direction on rational surfaces in Tokamak device has a suppression effect on the 3/1 double tearing modes instability,and the optimal initial localized driven current is current with Icd=4％I and δcd=0.07a.In addition,only when the localized driven current is injected before the fast growth stage,the double tearing modes can be suppressed.关键词
