    "abstract": "Ballooning instabilities are investigated in three-dimensional magnetic\ntoroidal plasma confinement systems with low global magnetic shear. The lack of\nany continuous symmetry in the plasma equilibrium can lead to these modes being\nlocalized along the field lines by a process similar to Anderson localization.\nThis produces a multibranched local eigenvalue dependence, where each branch\ncorresponds to a different unit cell of the extended covering space in which\nthe eigenfunction peak resides. These phenomena are illustrated numerically for\nthe three-field-period heliac H-1, and contrasted with an axisymmetric\n$s$-$\\alpha$ tokamak model. The localization allows a perturbative expansion\nabout zero shear, enabling the effects of shear to be investigated.",
