摘要
The penetrations of the parallel and perpendicular components of plasma currents are interrelated to each other due to the existence of magnetic shear in a tokamak configuration.Effects of the shear on the penetration of Fourier components of toroidal plasma current are analysed in a cylindrical column model.The current penetration is obviously strengthened by the shear for a bell-like conductivity profile and low safety factor and low aspect ratio.
