With solving the plasma equilibrium equation, ray equations and quasi-linear Fokker-Planck equation, the ray trajectories and power deposition of EC wave were numerically simulated in non-circular HL-2A Tokamak plasmas. The results show that when EC waves are launched from the top, the rays propagate towards the low-field side in non-circular plasma compared with the circular one, and the same effect occurs with increasing the central density of electrons, and the power deposition decreases accordingly. When the EC waves of ordinary mode are launched from the mid-plane and low-field-side, ray ...
