Abstract

The global stability of plasmas with helical boundary deformation and non null net toroidal current is tested against external n = 1 (n toroidal mode number) modes with the aim of seeing whether these modes can be stabilized at values of beta inaccessible for the classical tokamak. L=2,3 configurations with several aspect ratios and different numbers of equilibrium field periods are considered. A large variety of toroidal current densities are taken into account and Mercier stability is also investigated.
