The helicon current drive system for the efficient off-axis current drive of KSTAR is currently being upgraded with 476 MHz, 1.2 MW klystrons and a new high-voltage power supply (HVPS). Four klystrons, which were used in PEP-II, were transferred to N

A helicon wave was tested for coupling at low power in the KSTAR, and high-power coupling has also been tried. When RF is applied to the antenna system, the reflected power gradually increases on a sub-millisecond timescale. A slower process than usu

For the high-power and long-pulse ion cyclotron range of frequencies (ICRF) heating of the KSTAR plasma, we developed the compact ICRF antenna (CIA). The target injection power of CIA is 2 MW for 300 s. In order to continue injecting the power into p
