Stabilization study of the magnetohydrodynamic instability deciding the highest plasma pressure.

提高血浆β值对于聚变堆的实现是非常重要的。我们对阻性墙模式的稳定化进行了研究，最终限制了贝塔值。阐明了能量驱动模式触发RWM的机理。研究了具有极小线圈和极少线圈的RWM的稳定性问题。然而，在一定的条件下，由于控制线圈的尺寸较小，观察到了边带效应的3D效应对等离子体的降解。

It is very important to increase the plasma beta value for realization of the fusion reactor. We conducted a research on stabilization of resistive wall mode, which finally limit the beta value. The mechanism of RWM triggered by energetic driven mode has been clarified. Stabilization of RWM with very small and few coils has been clarified. However, under certain conditions, the degradation of plasma by 3D effect of sideband effect due to small size of the control coils has been observed.
