Abstract

Plasma current drive is one of critical problems to be solved in the development of fusion reactors under steady operation of low aspect ratio tokamak. DC helicity injection that has been used for the current drive of spheromak plasmas has also been successfully applied to low A tokamak plasmas. In this paper, the analytical expression of the equilibrium configuration has been derived for low A tokamak plasmas with a rectangler cross section. Two types of electrode configurations for the helicity injection, one the coaxial type, and the other the polar type, are considered. The condition of q profiles that provide the reversal magnetic shear are studied.
