Abstract :
Magnetohydrodynamic (MHD) equilibria of an axisymmetric compact torus with a fixed boundary are analyzed using the boundary element method (BEM). An iterative method is used to obtain nonlinear solutions and study the effects of the injecting part of plasma and a center conductor. Both the force-free and the rigid drift configuration are analyzed, and the magnetic flux for the numerical model of the CTCC-I spheromak device at Osaka University (Japan) is calculated. It is shown that the BEM is useful to study nonlinear configurations of a compact torus
