Abstract

Ion-temperature-gradient-driven instabilities are now commonly held responsible for turbulence giving rise to anomalous radial energy transport in the core of tokamaks. The work presented in this paper is the application of the particle methods to simulate the fully nonlinear time evolution of these instabilities in axisymmetric toroidal plasmas. The physical model is based on the gyrokinetic equation for the ions, the adiabatic response for the electrons, the quasi-neutrality condition and the electrostatic approximation.
