Calculation of Magnetic Field in J-TEXT with an Unsaturated Iron Core

摘要

A study of the magnetic field with an unsaturated iron core in tokamak equilibriumusing a spool model is described in detail. The application of this model to the J-TEXT tokamakshows that the calculated results are in good agreement with those measured experimentally. Atpresent this scheme is used to give the plasma configuration during J-TEXT's operation.
