Physics Design of the HL-2A Tokamak(In Chinese)

An overview report for the physics design of the HL-2A tokamak is presented.By numerically analyzing the plasma shaping and the vertical instability due to plasma elongation,the requirements for the currents of poloidal magnetic field coils and the control system are put forward.Controlling the plasma profile by using NBI(neutral beam injection) and LHCD(lower hybrid current drive) is investigated,and the high performance modes of operation in HL-2A are modeled and designed.The magnetohydrodynamic instabilities in improved confinement configuration(RS configuration) are studied so as to point out the way of plasma control to perform stationary high performance discharges in HL-2A.In order to offer data for updating the HL-2A divertor,performances of the divertor plasma are simulated.
