内容記述 | "Recent Large Helical Device experiments show that the transport modeling based only on the fluid description is not suf cient for expressing transport phenomena in/around an m=n = 1=1 magnetic island formed at the edge, and that neoclassical effect should be considered in order to understand the edge transport phenomena, where m is the poloidal mode number and n the toroidal mode number. To study the edge transport phenomena, we develop a new transport simulation code, KEATS, treating the neoclassical theory in/around the island. The code is programmed by expanding a well-known Monte-Carlo particle simulation scheme based on the delta f method for taking account of the neoclassical effect. The guiding center distribution function of plasma is separated into a local Maxwellian background fM and a kinetic part delta f considered as a small perturbation from fM. To treat evolution of the kinetic part delta f, we solve the linearized drift kinetic equation of the first order. In the modeling, evolution of the background fM described by fluid equations is also considered self-consistently with the kinetic part delta f. In this paper, we present the modeling used in the KEATS code, and show the simulation results in a test calculation." | |||||
