(In Chinese) GAO Qingdi LI Fangzhu ZHANG Jinhua PAN Yudong JIAO Yiming CSouthwestern Institute of Physics , Chengdu , 61004 1) ABSTRACT An overview report for the physics design of the HL-2A tokamak is pres- ented. By numerica l1y analyzing the plasma shaping and the vertical instability due to plasma elongation , the requirements for the currents of poloidal magnet- ic field coils and the control system are put forward. Controlling the plasma profile by using NBI Cneutral beam injection) and LHCD Clower hybrid current drive) is investigated , and the high performance modes of operation in HL-2A are modeled and designed. The magnetohydrodynamic instabilities in improved confínement configuration CRS 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. Key words: HL-2A , Physics design , Overview
