We present first principles simulations of the direct collisionless couplingof the free energy of fusion-born ions into electron current in a magneticallyconfined fusion plasma. These simulations demonstrate, for the first time, akey building block of some "alpha channelling" scenarios for tokamakexperiments. A fully self-consistent electromagnetic 1D3V particle-in-cell codeis used to evolve a parallel drifting ring-beam distribution of 3MeV protons ina 10keV thermal deuterium-electron plasma with realistic mass ratio. Collectiveinstability gives rise to electromagnetic field activity in the lower hybridrange of frequencies. These spontaneously excited obliquely propagating wavesundergo Landau damping on resonant electrons, drawing out an asymmetric tail inthe distribution of electron parallel velocities, which carries a current.
