Ripple loss reduction resulting in reduced losses of fast ions was demonstrated successfully at the JFT-2M tokamak by installing ferritic plates between the vacuum vessel and toroidal field coils. This paper describes the comparison between the experimental results and computation based on the orbit following a Monte Carlo code. They are in qualitatively good agreement in the cases where the toroidal distribution of the toroidal field ripple is almost periodic (e.g. ferritic plate installed resulting in a complex periodic structure of the magnetic ripple), but differ in the case of toroidally small average ripple exhibiting non-periodic large local ones (e.g. ferritic plate installed resulting in a more complex non-periodic structure of the magnetic ripple).

リップル損失の低減による高速粒子損失の減少が、真空容器とトロイダル磁場コイルの間にフェライト板を設置することにより、JFT-2Mトカマクにおいて実証に成功した。本論文では、実験結果と、モンテカルロコードに基づく軌道追跡計算との比較について述べる。両者は、トロイダル磁場リップルの分布がほぼ周期的である場合(例えば、フェライト板の設置により複雑な周期構造の磁気リップルが生じる場合)には定性的に良好な一致を示すが、トロイダル方向の平均リップルが小さく、局所的な非周期的な大きなリップルを示す場合(例えば、フェライト板の設置によりより複雑な非周期構造の磁気リップルが生じる場合)には差異が見られる。
