在DIII-D TOKAMAK中维持了归一化等离子压力的值，最高是理想磁流失动力学（MHD）理论预测的自由晶体稳定性极限的两倍。长波长模式通过电阻壁和快速的等离子体环旋稳定。高旋转速度通过最小化非轴对称磁场而维持，克服了长期存在的障碍[E. E. J. Strait，物理。莱特牧师。 74，2483（1995）]]。用理想壁计算的理想MHD压力极限被观察到归一化等离子体压力的操作极限。
Values of the normalized plasma pressure up to twice the free-boundary stability limit predicted by ideal magnetohydrodynamic (MHD) theory have been sustained in the DIII-D tokamak. Long-wavelength modes are stabilized by the resistive wall and rapid plasma toroidal rotation. High rotation speed is maintained by minimization of nonaxisymmetric magnetic fields, overcoming a long-standing impediment [E. J. Strait, Phys. Rev. Lett. 74, 2483 (1995)]]. The ideal-MHD pressure limit calculated with an ideal wall is observed as the operational limit to the normalized plasma pressure.
