A Iarge-aspect-ratio(LAR), midsize, diverted tokamak KT-2 with intense RF heating(5–7 MW) is under conceptual design process at KAERI. The machine parameters are: R/a(m) = 1.4/0.25 (reduceable to 0.20), B_t = 3 Tesla, I_p = 500+ kA, current flat-top 4.5 sec at maximum field and current (OH-only). The PF system concept design resulted in five KT-2 operation modes, and allows extended discharges for >30sec at 2T/200kA in the “5MW HiBS” mode. Construction will start in 1995, and the machine will start operation in 1998.
