Determination of best operation parameters of electron cyclotron wall conditioning in KSTAR

Determination of best operation parameters of electron cyclotron wall conditioning in KSTAR

Dependence of EC injection power (0.6 and 1.4 MW), EC injection width (0.1–1.0 s) and prefilled He pressure (2.8×10−5∼2.2×10−3 mbar) on D2 outgas efficiency is investigated at a toroidal field of 2.4 T in a poloidal trapped particle configuration with an EC wave frequency of 140 GHz (X-mode) and a s...
