Abstract
Turbulent transport in the inner core of the high-β JET hybrid discharge 75225 is investigated extensively through linear and non-linear gyro-kinetic simulations using the gyro-kinetic code GKW in the local approximation limit. Compared to previous studies [J. Citrin et al. 2015 Plasma Phys. Control. Fusion 57 014032, J. Garcia et al. 2015 Nucl. Fusion 55 053007], the analysis has been extended towards the magnetic axis, ρkθ ρi micro-tearing modes that are linearly stable. An extension of the quasi-linear models is proposed allowing better capturing the magnetic flutter flux.Keywords
