AbstractThe plasma initiation and the disruption observed in JT-60U experiment are simulated by using TSPS (Toroidally Symmetric Plasma Simulation) code and EDDYCAL code. TSPS code simulates plasma evolutions and EDDYCAL code performs the eigenmode analysis of the eddy currents. The agreements between the experiment and the simulation are acceptable. The maximum discrepancy of the vessel currents between the simulation results and the experimental measurements is about 30%. The plasma initiation is simulated from the initial magnetization until the plasma current grows 120 kA. It is found that the location of the initial plasma growth is determined by the positional stability. The negative voltage spike during the li-drop and the evolution of the plasma obtained in the simulation of the disruption are consistent with the experiment. It is shown that the simulation of the plasma with runaway electrons is possible if the information on the runaways is provided. The field configuration, which is responsible to the generation of runaway electrons, is discussed.

抄録JT-60U実験で観測されたプラズマ立ち上げとディスラプションを、TSPS(トロイダル対称プラズマシミュレーション)コードとEDDYCALコードを用いてシミュレーションした。TSPSコードはプラズマの時間発展をシミュレーションし、EDDYCALコードは渦電流の固有モード解析を行う。実験とシミュレーションの一致は許容範囲内である。シミュレーション結果と実験測定値間の vessel 電流の最大不一致は約30%である。プラズマ立ち上げは、初期磁化からプラズマ電流が120 kAに成長するまでシミュレーションされる。初期プラズマ成長の位置は位置安定性によって決定されることが見出された。li低下中の負の電圧スパイクと、ディスラプションのシミュレーションで得られたプラズマの時間発展は実験と一致する。 runaway 電子に関する情報が提供されれば、runaway 電子を含むプラズマのシミュレーションが可能であることが示される。runaway 電子の生成に関与する磁場配位について議論される。
