数值模拟获得了恢复饱和理想扭结/剥离结构的三维自由边界磁流体动力学平衡。对固定 <β>=1.7% 的 JET 托卡马克进行模拟，并使用大边缘自举电流使等离子体边界附近的 q 分布变平，结果表明，当环形电流 It 增加到 2.5 MA 时，在 It=2.2 MA 处具有主要 m /n = 5/1 傅立叶分量的径向平行电流密度带会发展成宽带谱。
Three dimensional free boundary magnetohydrodynamic equilibria that recover saturated ideal kink/peeling structures are obtained numerically. Simulations that model the JET tokamak at fixed 〈β〉=1.7% with a large edge bootstrap current that flattens the q-profile near the plasma boundary demonstrate that a radial parallel current density ribbon with a dominant m /n = 5/1 Fourier component at It=2.2 MA develops into a broadband spectrum when the toroidal current It is increased to 2.5 MA.
