Abstract

Abstract:

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.
