Abstract

We study here low frequency electrostatic microinstabilities driven by ion temperature gradients (ITG instabilities) relevant to anomalous ion heat transport in tokamaks. The plasma is modelled with gyrokinetic ions and adiabatic electrons. An axisymmetric equilibrium magnetic structure is provided by the magnetohydrodynamic (MHD) equilibrium code CHEASE. The full plasma cross-section is considered in the simulations. We follow the time-evolution of electrostatic, quasineutral perturbations of a local Maxwellian equilibrium distribution function, using 2 different particle-in-cell (PIC) codes running on a massively parallel CRAY-T3D.
