Reconstruction of Current Profiles and q Profiles on the HL-1M Tokamak

  • Published Date: January 31, 1999
  • The algorithm for reconstructing plasma current and safety factor profiles on a tokamak with an iron core transformer is given and applied to the analysis of experimental data. It is shown that a central negative magnetic shear region is realized througth ajusting the ramp-up rate of plasma current in ohmic discharges and through lower hybrid current drive on HL-1M tokamak.
