Abstract:
We have developed an advanced electrostatic macro-scale implicit particle simulation code (AMACS-ES), which enables us to simulate low-frequency plasma wave phenomena with large spatial scale length. Especially, the Poisson's equation with the implicit susceptibility term is accurately solved in our algorithm. Linear properties of the simulation code based on this algorithm, such as the linear stability and the dispersion relation, are examined. We have also applied our simulation code to the excitation and nonlinear saturation of the ion temperature gradient (ITG) drift instability in a system with a shearless slab geometry. The linear properties of the excited ITG mode are compared with the theoretical prediction to find a good agreement.
