被引用回数：38 パーセンタイル：86.74(Physics, Fluids & Plasmas)Extensive physics analysis and modelling has been undertaken for the typical operational regimes of the tokamak devices JET and JT-60U with the aim of extrapolating present day experiments to JT-60SA, which shares important characteristics with both tokamaks. A series of representative discharges of two operational scenarios, H-mode and hybrid, have been used for this purpose. Predictive simulations of core turbulence, particle transport, current diffusion and pedestal pressure have been carried out with different combinations of models. The ability of the models for reproducing the experimental data is analysed and scenario calculations for JT-60SA are performed following an optimum set of models.

被引用回数：52 パーセンタイル：87.41(Physics, Fluids & Plasmas)本論文では、ASDEX-U, DIII-D, HL-2A, JET, JT-60U, MAST, NSTX, TCV, Tore Supraにおいて鋸歯状振動と新古典テアリングモード(NTM)の発生について調べた結果について記述している。データベース解析の結果、鋸歯状振動がNTMを誘起したときのベータ値は鋸歯状振動の周期とともに低下することがわかった。また、装置間で鋸歯状振動を比較する場合、鋸歯状振動周期を抵抗性拡散時間で規格化し、プラズマ圧力として規格化ベータ値(

でNTMが誘起されると予想されるのに対し、鋸歯状振動周期が100秒の場合は
でNTMが誘起されると予想されることがわかった。

An extensive exercise of physics analysis and modeling has been undertaken for the typical operational regimes of the tokamak devices JET and JT-60U with the aim of extrapolating present day experiments to JT-60SA, which share characteristics with both tokamaks. A series of representative discharges of two operational scenarios, H-mode and hybrid have been used for this purpose. Predictive simulations of core turbulence, particle transport, current diffusion and pedestal pressure have been carried out with different combination of models. The ability of the models for reproducing the experimental data is analyzed and scenario calculations for JT-60SA are performed following an optimum simulation framework.
