Abstract
The algorithm for reconstructing plasma current and safety factor profiles on a tokamak with an iron core transformer is given and applied to the anal ysis of experimental data. It is shown that a central negative magnetic she ar region is realized through adjusting ramp-up rate of plasma current in o hmic discharges and through lower hybrid current drive on HL-1M tokamak.
