KSTAR interior during an Ohmic plasma discharge at 210 frames/s, 3 ms experimental time, shot 794 as taken with the visible/H-alpha TV on the A median port: (a) start of ECH preionization at , (b) Ohmic plasma formed at due to the superconducting PF magnet coil current discharge, (c) plasma current reached 107 kA for the first time at , and (d) plasma hit the inboard tile just before it died out at .
Time evolution of plasma parameters during a plasma discharge (shot 794): total currents from VCMs, plasma currents from RCs, and a loop voltage from a flux loop.
