  要:

Radiofrequency wave in ion cyclotron range of frequency (ICRF) is an important way for heating plasma, driving current and implementing plasma control in the magnetic fusion devices such as EAST and ITER tokamak. Achieving good coupling of ICRF power into the plasma is an essential issue for high power ICRF injection on EAST tokamak. In this talk, we present the Modeling of ICRF power injected into 3D EAST plasmas via the high performance Finite-difference time-domain (FDTD) model in VSim software. Realistic 3D ICRF antenna module and box of the B-port on EAST have been constructed as geometry in the simulations. The effects of antenna structure, antenna phase, minority ion, distance between antenna and plasma, and toroidal curvature on the ICRF coupling and propagation are discussed.
