Development of 20s long hybrid scenarios on JET

This paper reports the results of recent experiments carried out at JET achieving a stationary hybrid scenario lasting 20s with dN�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.
