Abstract: The equilibrium fiting code (EFIT) is used to design the basic configurations which include the limiter, double null divertor and single null divertor configurations. These configurations with high elongation and large triangularity, meet the main configuration parameters given by the physical target of HL-2M tokamak: the major radius is 1.78 m and the minor radius up to 0.65m. In consideration of the influence of CS coil current on configurations and the limits of PF coils current, several discharges waveforms of three basic configurations was designed with the plasma current equal to 1.2MA which is the normal current for the HL-2M discharge schemes. The other discharges waveforms with the plasma current equal to 3MA are designed also. In addition, the volt-seconds consumption is analyzed by tokamak simulation code (TSC) for the HL-2M discharge evolution process with the plasma current equal to 1.2MA.

摘要： 利用EFIT为HL-2M装置设计了孔栏位形、双零偏滤器位形和下单零偏滤器位形三种典型平衡位形；三种位形满足HL-2M装置的物理目标给出的位形参数的总体要求，即大半径1.78m、小半径0.65m，且位形具有高拉长比、大三角形变等特点。同时充分考虑CS线圈电流对位形的影响和PF线圈电流限制，分别设计了等离子体电流为1.2MA和3MA的三种基本位形放电波形；利用TSC分析了等离子体电流为1.2MA的HL-2M装置放电演变过程中伏秒数消耗。
