✦ Synopsis

direct method for an electrostatic model is to make prediction of charge density based on a linearized approximation,

We have developed an electrostatic macro-scale implicit particle simulation code which enables us to simulate low-frequency plasma which depends only on particle positions, and to calculate wave phenomena with large spatial scale length. Specifically, the the electrostatic potential at the next time step. In addition, Poisson equation with the implicit susceptibility term is accurately an implicit equation of motion for each particle, which solved in our scheme with the ''strict differencing'' and ''the consisis numerically stable against the high-frequency plasma tent filtering.'' Linear properties of the simulation scheme, such as oscillation, is solved along with the Poisson equation which the linear stability and the dispersion relation, are examined. We have also applied our simulation code to the excitation and nonlinis modified with the implicit susceptibility term.

ear saturation of the ion temperature gradient (ITG) drift instability

In the macro-scale particle simulation scheme [5], which in a system with a shearless slab geometry. The linear properties is categorized in the direct implicit method, both the equaof the excited ITG mode are compared with the theoretical prediction tion of motion and the Maxwell equation are solved by to find a good agreement.
