Impurity ion transport modifications due to sawtooth internal disruptions during neutral-beam heating in TFR

TFR group1985年被引用 26Nuclear FusionIF 3出版社

Large sawtooth modulations on the radiance of central nickel ions during injection of hydrogen atoms into deuterium plasmas could not be properly simulated by considering only the changes in the radial profiles of Te and ne. The impurity transport parameters had to be modified during the disruption, leading to expulsion of Ni ions from inside the q = 1 surface.

重水素プラズマへの水素原子注入中における中心ニッケルイオンの放射輝度に見られる大きな鋸歯状変調は、Te および ne の動径分布の変化のみを考慮しただけでは適切にシミュレーションできなかった。擾乱中に不純物輸送パラメータを修正する必要があり、その結果、q = 1 面の内側から Ni イオンが排出された。
