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

提高等离子体的β值对于实现聚变反应堆是非常重要的。我们对阻壁模的稳定化进行了研究，最终限定了beta值。阐明了能量驱动模式触发RWM的机理。阐明了小线圈RWM的稳定问题。然而，在一定条件下，由于控制线圈尺寸小，等离子体被边带效应的三维效应降解。

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.
