Abstract :
A large-aspect-ratio (LAR), midsize, diverted tokamak KT-2 with intense heating (8-10 MW) has entered the construction phase at KAERI. The machine parameters are: R/a=1.4/0.25 m, Bt=3 Tesla, Ip=500+ kA, current flat-top of minimum 4.0 sec at maximum field and current (OH-only). The PF system design resulted in three major KT-2 operation modes. The “5 MW HiBS” mode, which utilizes higher bootstrap current fraction, allows extended discharges for >20 sec at 2 T/300 kA. The machine will start operation by the end of 1998
