摘要: A general geometry gyro-kinetic model for particle simulation of plasma turbulence in tokamak experiments is described. It incorporates the comprehensive influence noncircular cross section, realistic profiles, rotation, neoclassical (equilibrium) electric fields, and Coulomb collisions. An interesting result global development a shaped presented with regard to nonlinear spreading into linearly stable region. The mutual interaction between zonal flows collisionless plasmas studied focus on identifying possible saturation mechanisms flows. bursting temporal behavior period longer than geodesic acoustic oscillation observed even system. Our results suggest that can drive turbulence. However, this process too weak be an effective flow mechanism.
