Electron Current Drive by Fusion-Product-Excited Lower Hybrid Drift Instability
Electron Current Drive by Fusion-Product-Excited Lower Hybrid Drift Instability
We present first principles simulations of the direct collisionless coupling of the free energy of fusion-born ions into electron current in a magnetically confined fusion plasma. These simulations demonstrate, for the first time, a key building block of some "alpha channelling" scenarios for tokamak experiments. A fully self-consistent electromagnetic 1D3V …
