title: Magnetic-surface quality in nonaxisymmetric plasma equilibria.
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.
