On the reduction of magnetic islands, residues in HS 5-7
Creators
Description
A systematic method is applied to reduce the size of magnetic islands in vacuum field configurations where the magnetic fields are given by a set of Dommaschk potentials of low order. In typical cases, fields with 3, 5, 10, 12 toroidal field periods and poloidal mode numbers up to 4 (including axisymmetric fields) define a last closed magnetic surface with aspect ratio A ≅ 11 to 13 and rotational transfor τb=5/7 near the boundary. Cross sections of magnetic surfaces are plotted at 0, Lp/4, Lp/2 of a field period. (orig.)
