Global analysis of tungsten migration in WEST discharges using numerical modelling
Plasma discharges in the tungsten (W) Environment kakespade Steady-state Tokamak (WEST) are strongly impacted by W contamination.In WEST experiments, due to W contamination, the power radiated in the plasma ( P _Rad ) is on average, around 50% of the total power injected into the plasma ( P _TOT ).Furthermore, this radiated power fraction ( f _Rad
