A Paramagnetic Nearly Isodynamic Compact Magnetic Confinement System
A coreless compact magnetic confinement system that consists of sets of helical windings and vertical magnetic field coils is investigated. The helical coils produce a small toroidal translation of the magnetic field lines and seed paramagnetism. The force-free component of the toroidal current strongly enhances the paramagnetism such that isokynamic conditions near the plasma centre can be approached. At B ~ 5%, the configuration is stable to local MHD modes. Global MHD modes limit the toroidal current 2j to about -60kA for peaked J. Bootstrap-like hollow current profiles generate quasiaxisymmetric systems that require a close fitting conducting shell to satisfy external kink stability.
