Ion Cyclotron Resonance Heating in WEST

Abstract: In a fusion power plant the plasma must be confined to prevent instabilities and energy loss. The confinement machine studied is a tokamak. The focus of the project is to optimize ion resonance heating in WEST. The code called FEMIC was used to simulate different scenarios where parameters such as ion concentrations, antenna frequency are analysed for the case of minority hydrogen in deuterium plasma. The optimal Hconcentration in D-plasma was found to be 10 5%, which allows for a wide concentration interval. However, the strongest coupled power was found to be at the H-concentration of 6%. Thus, the optimal concentration for strongest coupled power and H-minority absorption is 6% in WEST for the case of Hydrogen minority in Deuterium plasma.
