In- and outboard Plasma Facing Components (PFCs) of KSTAR (Korea Superconducting Tokamak Advanced Reasearch) have been fully installed in 2010 for D shaped diverted plasmas. Before the start of plasma operation, the PFCs were baked up to 200 °C by hot nitrogen gas circulation system to remove impurities including water. The surface temperature of the PFC tiles was monitored by 200 thermo-couple sensors...
The Korean Superconducting Tokamak Advanced Research (KSTAR) device is aimed at advanced tokamak (AT) research. Three years have passed since it achieved its first plasma in 2008. Because it is a superconducting machine and is pursuing AT research, it has unique features in terms of the machine engineering and operation. The toroidal field (TF) magnet coils are made of Nb3Sn, which provide high toroidal...
