概要

Vacuum magnetic fields in helical configurations are analyzed by using the scalarpotential which satisfies Laplace equation. By adding the axisymmetric toroidal andvertical magnetic fields to the helical field, the nested magnetic surfaces are con-structed. The rotational transform, aspect ratio, specific volume and helical rippleratio are calculated for the l=2 stellarator/heliotron/torsatron configurations (/;multipolarity of the field) for various values of m (m; toroidal pitch number). Themagnetic sturface is optimized in regard to the rotational transform and the area surrounded by the outermost magnetic surface. The generation of the magnetic well andthe increment of the confinement region by the vertical field are also discussed.Finally, the nz=2 low aspect ratio system is discussed.
