Description
A new LHCD antenna has been designed for HL-2A tokamak in passive active multijunction (PAM) form. Thermal analysis of the antenna has been done by finite element method, which shows that oxygen free copper can meet the thermal requirements. Electromagnetic analysis is carried out by analytic method under varying toroidal magnetic field and plasma current conditions. It is demonstrated that a pair of torque generated by the electromagnetic torsion may destroy the antenna when plasma disrupts, and stainless steel can satisfy the torque requirements. Combining oxygen free copper and stainless steel may be a reasonable solution in the practical manufacturing process. This work provides theoretical basis for the development of the new antenna.
