Abstract

The confinement of plasmas by magnetic fields with nonaxisymmetric shaping can be degraded or destroyed by the breakup of the magnetic surfaces through effects that are intrinsic to the shaping. An efficient perturbation method of determining this drive for islands was developed and applied to stellarator equilibria.

摘要

通过具有非轴对称形状的磁场对等离子体进行约束，可能会因形状本身所固有的效应导致磁面破裂，从而使约束性能下降或遭到破坏。一种确定这种岛驱动的有效微扰方法被开发出来，并应用于仿星器平衡态。
