Analytical Expression of Equilibrium Configuration of Low Aspect Ratio Tokamaks with Helicity Injection

摘要

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 successfully applied to low A tokamak plasmas. In this paper, the analytical expression of the equilibrium configuration has been derived for low A tokamak plasma with a rectangler cross section .
