摘要：
Recent experiments of Experimental Advanced Superconducting Tokomak (EAST) have successfully demonstrated a long-pulse steady-state scenario with improved plasma performance through integrated operation. The helicon wave (fast wave at omega > 20 omega(ci)) current drive in the EAST plasma with high beta(e) operation is studied numerically by means of GENRAY/CQL3D treatment. A theoretical analysis of the wave damping factor shows that electron Landau damping dominates the wave absorption process and effective current drive occurs in the central plasmas for low beta(e) operation. High beta (simi...
