Electron-cyclotron resonance heating and current drive source for flux-driven gyrokinetic simulations of tokamaks

Stefano Coda, Laurent Villard, Stephan Brunner, Joan Decker, Jean Arthur Cazabonne

Electromagnetic waves that resonate with the cyclotron motion of electrons in a magnetized plasma can efficiently transfer their momentum and energy to the plasma. This is routinely used to heat or drive current in tokamak plasmas. The impact of this local ...
