New features of the energy confinement were observed in the Ohmic regime with reduced transport - Ohmic H-mode. Parametric dependencies as well as absolute values of the energy confinement time are in agreement with scaling proposed for description of the ELM-free H mode in bigger devices with powerful auxiliary heating ("DIII/JET H-mode" scaling). In particular, strong dependencies of tau E on plasma current and input power and weak dependencies on density were found. Energy confinement time is enhanced by a factor of 15 compared to predictions of the usual ohmic scalings ("Neo-Alcator", "Merezhkin-Mukhovatov"). In the small tokamak TUMAN-3 30ms energy confinement time was achieved.

オーミック領域におけるエネルギー閉じ込めの新たな特徴が、輸送が低減したHモードで観測された。エネルギー閉じ込め時間のパラメータ依存性および絶対値は、大型装置における強力な追加加熱を伴うELMフリーHモードを記述するために提案されたスケーリング(「DIII/JET Hモードスケーリング」)と一致する。特に、τ_Eのプラズマ電流および入力電力に対する強い依存性と、密度に対する弱い依存性が見出された。エネルギー閉じ込め時間は、通常のオーミックスケーリング(「Neo-Alcator」、「Merezhkin-Mukhovatov」)の予測と比較して15倍向上した。小型トカマクTUMAN-3において、30msのエネルギー閉じ込め時間が達成された。
