Quadrupole configurations with a : non-uniform plasma current are considered. The configurations are not so much the improvement of Tokamak geometry as the hybrid between ZETA and Multipoles. A very deep magnetic well and a strong shear may be realized even in the straight configurations.
In the earlier paper we have discussed a unipue solution of the magnetiostatic equlibrium for a one-dimensianl system, by making use of London's equation. In this short paper we have obtained the equilibrium congiguration of the Bennett pinch
