用SWEQU平衡态程序模拟了HL-2A装置的单零偏滤器和双零偏滤器位形。在第一次物理运动中，偏滤器下部放电是通过多极场线圈的两种供电方式实现的。利用可见光摄影、靶探针阵列和重建的磁表面，确定了单零偏滤器位形。用18个Mirnov信号重构多电流丝编码，得到等离子体柱的磁分界线和短半径。
Single- and double-null divertor configurations in HL-2A are simulated by SWEQU equilibrium code. Lower divertor discharges in the first physics campaign have been achieved by two kinds of power supply method of multipole-field coils. Single-null divertor configuration has been identified by visible photography, target probe arrays and the reconstructed magnetic surface. Magnetic separatrix and minor radius of plasma column are obtained by a reconstructed code of multiple current filaments using 18 Mirnov signals.
