We present a study of the power threshold for L–H transitions (PLH) in almost pure helium plasmas, obtained in recent experiments at JET with an ITER-like wall (Be wall and W divertor). The most notable new result is that the density at which PLH is minimum, , is considerably higher for helium than for deuterium and hydrogen plasmas. We discuss the possible implications for ITER in its pre-fusion operating power phase.

我々は、ITER類似壁(Be壁とWダイバータ)を備えた最近のJET実験で得られた、ほぼ純粋なヘリウムプラズマにおけるL-H遷移のパワー閾値(PLH)に関する研究を発表する。最も顕著な新しい結果は、PLHが最小となる密度が、重水素および水素プラズマと比較してヘリウムプラズマではかなり高いことである。我々は、ITERの核融合前運転出力段階におけるこれらの結果の潜在的影響について議論する。
