| 摘 要： | 在HL-2M托卡马克平衡位形(Ip=1.0MA,βN=1.62,q95=4.01)下,使用环形单流体程序MARS-F研究了等离子体对共振磁扰动(RMP)线圈电流相位差的响应.在最优相位差时,扰动磁场显著地改变边界层磁场的拓扑,形成明显的磁岛链,增加了等离子体在边界层的输运,降低了压强梯度,减小了对ELM的驱动.模拟结果...

| Abstract: | Using the toroidal single-fluid code MARS-F, the plasma response to the phase difference of the resonance magnetic perturbation (RMP) field coil currents is studied in HL-2M equilibrium configuration (Ip=1.0MA, βN=1.62, q95=4.01). At the optimal phase difference, the perturbing magnetic field significantly changes the topology of the magnetic field in the boundary layer, forms obvious magnetic island chains, increases the transport of plasma in the layer, and reduces the pressure gradient and the drive to the ELM. The optimal phase differences are about 180°, 150° and -30° for the n=1, 2 and 4 toroidal modulus of the disturbance fields, , respectively. |
