Tungsten impurity reduction by ICRH in a high power injection and high performance H-mode discharge on EAST

Tungsten impurity reduction by ICRH in a high power injection and high performance H-mode discharge on EAST

The decrease in tungsten (W) content with the higher ion cyclotron resonance heating (ICRH) power is observed and explained for the first time in a high power injection ( P _inj > 10 MW), high performance ( β _N ∼ 2, β _P ∼ 2.8, n _e / n _GW ∼ 80%, f _BS ∼ 60%) H-mode discharge on experimental ad...
