对施加场磁等离子体动力推进器中的磁和静电涨落的测量表明，只要违反克鲁斯卡尔-沙弗拉诺夫极限，m/n=1/1 扭结模式就会变得不稳定。高电流下的扭结和性能下降之间存在正相关关系，到目前为止，这阻碍了这种推进器在太空任务中的使用。
Measurements of magnetic and electrostatic fluctuations in an applied field magneto-plasma-dynamic thruster have shown that a m/n=1/1 kink mode becomes unstable whenever the Kruskal-Shafranov limit is violated. A positive correlation is established between the kink and performance degradation at high current, which has until now prevented the use of this kind of thruster in space missions.
