Simulations of Turbulent Plasma Heating by Powerful Electron Beams

Fusion Science and Technology / Volume 59 / Number 1T / January 2011 / Pages 70-73

Basic mechanisms of turbulent plasma heating by powerful electron beams are studied using numerical simulations. Both particle-in-cell and hybrid codes are used to investigate how beam-plasma instability evolves and saturates in the case of continuously injected electron beam. For sufficiently high plasma temperature beam driven turbulence is found to operate in the regime of the constant pump, when the saturation level of heating power is determined solely by beam nonlinearities.
