Recent progress towards a quantitative description of filamentary SOL transport
D. Carralero, M. Siccinio, M. Komm +22
A summary of recent results on filamentary transport, mostly obtained in the ASDEX-Upgrade tokamak (AUG), is presented and discussed in an attempt to produce a coherent picture of…
Contrasting H-mode behaviour with deuterium fuelling and nitrogen seeding in the all-carbon and metallic versions of JET
G. P. Maddison, C. Giroud, B. Alper +48
The former all-carbon wall on JET has been replaced with beryllium in the main torus and tungsten in the divertor to mimic the surface materials envisaged for ITER. Comparisons are…
Experimental validation of a filament transport model in turbulent magnetized plasmas
D. Carralero, P. Manz, L. Aho-Mantila +9
In a wide variety of natural and laboratory magnetized plasmas, filaments appear as a result of interchange instability. These convective structures substantially enhance transport…
Bayesian modelling of the emission spectrum of the JET Li-BES system
Sehyun Kwak, J. Svensson, M. Brix +2
A Bayesian model of the emission spectrum of the JET lithium beam has been developed to infer the intensity of the Li I (2p-2s) line radiation and associated uncertainties. The det…
Bayesian electron density inference from JET lithium beam emission spectra using Gaussian processes
Sehyun Kwak, J. Svensson, M. Brix +1
A Bayesian model to infer edge electron density profiles is developed for the JET lithium beam emission spectroscopy system, measuring Li I line radiation using 26 channels with ~1…
Identity of the JET M-mode and the ASDEX Upgrade I-phase phenomena
D. I. Réfy, E. R. Solano, N. Vianello +11
An H-mode plasma state free of edge-localized mode (ELM), close to the L-H transition with clear density and temperature pedestal has been observed both at the Joint European Torus…
Observation of confined current ribbon in JET plasmas
E. R. Solano, P. J. Lomas, B. Alper +29
we report the identification of a localised current structure inside the JET plasma. It is a field aligned closed helical ribbon, carrying current in the same direction as the back…
Real-time identification of the current density profile in the JET Tokamak: method and validation
Didier Mazon, Jacques Blum, Cédric Boulbe +6
The real-time reconstruction of the plasma magnetic equilibrium in a Tokamak is a key point to access high performance regimes. Indeed, the shape of the plasma current density prof…
