Effect of ion orbit loss on distribution of particle, energy and momentum sources into the tokamak scrape-off layer

W.M. Stacey2013年被引用 29Nuclear FusionIF 3出版社

The effect of ion orbit loss on the poloidal distribution of ions, energy and momentum from the plasma edge into the tokamak scrape-off layer (SOL) is analysed for a representative DIII-D (Luxon 2002 Nucl. Fusion42 614) high-mode discharge. Ion orbit loss is found to produce a significant concentration of the fluxes of particle, energy and momentum into the outboard SOL. An intrinsic co-current rotation in the edge pedestal due to the preferential loss of counter-current ions is also found.

トカマク周辺部からスクレープオフ層(SOL)へのイオン、運動量、エネルギーのポロイダル方向分布に対するイオン軌道損失の影響を、代表的なDIII-D(Luxon 2002 Nucl. Fusion42 614)高モード放電について解析した。イオン軌道損失により、粒子、運動量、エネルギーのフラックスが外側SOLに顕著に集中することが見出された。また、カウンター方向イオンの優先的な損失により、周辺ペデスタルにおいて本質的なコ方向回転が生じることも見出された。
