Numerical and experimental studies of simulated toroidicity effects in a linear high-beta heliac
Abstract
Formation and equilibrium studies of a linear high beta were performed, showing an axial current is induced. Vacuum field numerical studies have shown that when the hardcore center conductor is shifted, the magnetic field structure is similar to a large aspect ratio toroidal heliac. An experiment in a hardcore theta pinch has shown that programming of the hardcore current can significantly reduce the induced axial current. Finite beta effects were incorporated into a code to study the evolution of plasma on a shifted hardcore heliac. These results will be used in an experimental study of simulated toroidicity in a shifted hardcore linear heliac.
