Numerical simulation and analysis of electron cyclotron resonance heating effect on EAST

为了给EAST电子回旋共振加热物理实验提供理论依据和模拟预测,从电子热输运方程出发,运用CRONOS输运程序对不同等离子体和波参数下,电子回旋加热效果进行了数值模拟计算。给出不同电子回旋波功率、入射角、电子密度和纵场等参数对电子回旋加热效果的影响,预测在不同参数下,电子温度、等离子体总内能和能量约束时间的变化,分析了其原因,并与实验结果进行了初步的比较。

In order to provide theoretical reference and predictions for relevant physical experiments of electron cyclotron resonance heating（ECRH） on EAST, based on the electron transport equation, some numerical simulations of heating effect of ECRH in different plasma and electron cyclotron wave（ECW） parameters were carried out by using CRONOS transport simulation code. The dependences of the heating effect on ECW power, injection angle, electron density and toroidal magnetic field are given. The electron temperature, total internal energy and energy confinement time for different parameters are predicted and analyzed. Finally, the preliminary comparisons of simulation results and experimental results are discussed.
