Abstract:
Magnetic surface breaking due to the finite pressure effect is analyzed for three dimensional magnetohydrodynamic equilibria of l=2 Heliotron configuration. Characteristics of magnetic island formation are extensively surveyed. It is found that the well-hill criterion which has been predicted by the local analysis is not always applicable for all cases.
