Effect of stochastic ripple diffusion on the detection of fusion product ions by pellet charge exchange diagnostics

P.B. Parks, R.K. Fisher, J.M. McChesney1995年被引用 4Nuclear FusionIF 3出版社

The steady state velocity distribution of high energy fusion product ions subject to enhanced stochastic ripple diffusion is obtained analytically for a small but finite banana width. The distribution function is found to have a strong pitch angle dependence. This has important consequences in TFTR for alpha particle diagnostics using the pellet charge exchange (PCX) method since different detector lines of sight will correspond to different amounts of alpha particle depletion

高エネルギー核融合生成イオンの速度分布が、有限ではあるが小さいバナナ幅を有する強化確率的リップル拡散の条件下で、定常状態において解析的に求められた。この分布は強いピッチ角依存性を示すことが見出された。これはTFTRにおけるペレット荷電交換(PCX)法を用いたアルファ粒子診断において重要な意味を持ち、なぜなら検出器の視線方向が異なれば、アルファ粒子の減少度も異なることになるからである。
