The inverse problem of the MHD equilibrium of a plasma: determining the current density in a tokamak from measurements of the magnetic field outside the plasma column: is analyzed. A regularizing algorithm for solving the problem is proposed for the case in which the poloidal magnetic field at the plasma boundary is known. The results of a numerical simulation on the reconstruction of model current profiles in the T-15 and the INTOR are reported. These results illustrate the capabilities of the method.
