PB diagram of KSTAR discharge


Target KSTAR discharge is #7328 since we have clear ECEI observation data and toroidal mode analysis data from toroidal Mirnov coil array and toroidally separated two ECEI system.

At the current flat top, plasma current, Ip, is 750 (kA), toroidal magnetic field, BT, is 2.25 (T), safety factor at 95% poloidal flux, q95, is ~ 5 and the plasma is heated by ~3 (MW) neutral beam only.

At first, bootstrap current is calculated using Sauter’s formula.
