モンテカルロコード DEGAS を用いた中性粒子輸送シミュレーションの技法 -ガンマ10への適用-

Techniques for the neutral transport simulation using a Monte-Carlo code are briefly reviewed by explaining the examples of the simulation with the DEGAS Monte-Carlo code. Tandem mirror plasma produced in GAMMA 10 is employed as a target plasma for the simulation. An axisymmetric simulation using the ver.35 code is applied for the central-region and a three-dimensional simulation in non-axisymmetric anchor region is performed with the ver.63 code. In this review brief introduction of both versions, newly introduced processes and mesh models designed for axisymmetric and non-axisymmetric structures in the GAMMA 10 are described.
