Global scaling of the heat transport in fusion plasmas
Sara Moradi, Johan Anderson, Michele Romanelli +2
A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…
The role of MHD in causing impurity peaking in JET Hybrid plasmas
T. C. Hender, P. Buratti, F. J. Casson +10
In Hybrid plasma operation in JET with its ITER-like wall (JET-ILW) it is found that n>1 tearing activity can significantly enhance the rate of on-axis peaking of tungsten impuriti…
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…
Energetic particle instabilities in fusion plasmas
S E Sharapov, B Alper, H L Berk +41
Remarkable progress has been made in diagnosing energetic particle instabilities on present-day machines and in establishing a theoretical framework for describing them. This overv…
Time-Resonant Tokamak Plasma Edge Instabilities?
A. J. Webster, R. O. Dendy, F. A. Calderon +14
For a two week period during the Joint European Torus (JET) 2012 experimental campaign, the same high confinement plasma was repeated 151 times. The dataset was analysed to produce…
The effect of ITER-like wall on runaway electron generation in JET
G. Papp, T. Fülöp, T. Fehér +8
This paper investigates the effect of the ITER-like wall (ILW) on runaway electron (RE) generation through a comparative study of similar slow argon injection JET disruptions, perf…
Identifying low-dimensional dynamics in Type-I edge-localised-mode processes in JET plasmas
F. A. Calderon, R. O. Dendy, S. C. Chapman +4
Edge localised mode (ELM) measurements from reproducibly similar plasmas in the Joint European Torus (JET) tokamak, which differ only in their gas puffing rate, are analysed in ter…
Large-scale drifts observed on electron temperature measurements on JET plasmas
Thomas Gerbaud, Stefan Schmuck, Barry Alper +8
Between 1995 and 2009, electron temperature (Te) measurements of more than 15000 plasmas produced in the Joint European Torus (JET) have been carefully reviewed using the two main…
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…
