This paper reports the results of recent experiments carried out at JET achieving a stationary hybrid scenario lasting 20s with βN≈2. 5 and H89≈2. Up to 186 MJ have been injected in the plasma via Neutral Beams, with a significant fraction (up to 50%) of current density driven non-inductively. Emphasis is given to the plasma control features (boundary flux control, strike points sweeping and total plasma current control) that have allowed this achievement.

Abstract
This paper reports the results of recent experiments carried out at JET achieving a stationary hybrid scenario lasting 20s with βN≈2. 5 and H89≈2. Up to 186 MJ have been injected in the plasma via Neutral Beams, with a significant fraction (up to 50%) of current density driven non-inductively. Emphasis is given to the plasma control features (boundary flux control, strike points sweeping and total plasma current control) that have allowed this achievement.File in questo prodotto:
