Abstract
Indentation of a tokamak plasma on its inner-major-radius side is shown to be strongly beneficial for achieving high-β stability against ballooning modes. With use of a set of reasonable equilibrium profiles, it is found that moderate indentation provides accessibility to the second region of stability. Ohmic equilibrium configurations which exhibit the second stability region have not yet been found.
