Symmetrized magnetic field configuration of low aspect ratio helical system
Abstract
A helical system has the attractive feature such that it can generate the closed magnetic surface by externally wound coils alone. However, there are many problems to be solved for the confinement of a reactor grade plasma in helical systems. A new method is proposed for coil width modulation (modulation of the helical coil current distribution) to meet with the requirement for the magnetic configuration of a high temperature plasma confinement. This method can reduce multi-helicity (higher or satellite harmonics of the fundamental helical field) which brings many demerits into the conventional stellerator/torsatron/heliotron configuration.
