Nonlinear Dependence of the Synergetic Current by the Combined Effect of ECCD and LHCD on the Power Ratio on HL-2A Tokamak

Nonlinear dependence of the synergetic current by the combined effect of electron-cyclotron current drive (ECCD) and lower-hybrid current drive (LHCD) on the power ratio is shown through the recent simulation research based on common parameters on HL-2A tokamak. Corresponding experiments have been demonstrated on HL-2A tokamak and these experimental results verify qualitatively the simulated ones.
