An analysis of the toroidally shaped aeliotron field

Abstract

An analysis of the magnetic field produced by e current following in the toroidally wound deliotron coils i3 studied. Under the assumption that a radius of coils is much less than that of torus, the analysis can resort to the peiturbation methord which all quantities are expanded in ta, where kis curvature of torus and a is radius of coil.
Heliotron magnetic field is obtained analytically as a function of coil radius, the ratio of adjacent coils, the distance of adjacent coils and aurv_??_ture of torus. This field agrees with the experiment results.
