Flat-top plasma operational space of the STEP power plant
E. Tholerus, F. J. Casson, S. P. Marsden +16
STEP is a spherical tokamak prototype power plant that is being designed to demonstrate net electric power. The design phase involves the exploitation of plasma models to optimise…
Efficient training sets for surrogate models of tokamak turbulence with Active Deep Ensembles
L. Zanisi, A. Ho, T. Madula +7
Model-based plasma scenario development lies at the heart of the design and operation of future fusion powerplants. Including turbulent transport in integrated models is essential…
First-principles-based multiple-isotope particle transport modelling at JET
M. Marin, J. Citrin, C. Bourdelle +6
Core turbulent particle transport with multiple isotopes can display observable differences in behaviour between the electron and ion particle channels. Experimental observations a…
New plasma regimes with small ELMs and high confinement at the Joint European Torus
J. Garcia, E. de la Luna, M. Sertoli +15
New plasma regimes with high confinement, low core impurity accumulation and small Edge localized mode (ELMs) perturbations have been obtained close to ITER conditions in magnetica…
Flux-driven integrated modelling of main ion pressure and trace tungsten transport in ASDEX Upgrade
O. Linder, J. Citrin, G. M. D. Hogeweij +9
Neoclassical and turbulent heavy impurity transport in tokamak core plasmas are determined by main ion temperature, density and toroidal rotation profiles. Thus, in order to unders…
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…
Overview of recent physics results from MAST
A Kirk, J Adamek, RJ Akers +160
New results from MAST are presented that focus on validating models in order to extrapolate to future devices. Measurements during start-up experiments have shown how the bulk ion…
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…
Charge dependence of neoclassical and turbulent transport of light impurities on MAST
S. S. Henderson, L. Garzotti, F. J. Casson +8
Carbon and nitrogen impurity transport coefficients are determined from gas puff experiments carried out during repeat L-mode discharges on the Mega-Amp Spherical Tokamak (MAST) an…
Neoclassical and gyrokinetic analysis of time-dependent helium transport experiments on MAST
S. S. Henderson, L. Garzotti, F. J. Casson +8
Time-dependent helium gas puff experiments have been performed on the Mega Ampere Spherical Tokamak (MAST) during a two point plasma current scan in L-mode and a confinement scan a…
Theoretical description of heavy impurity transport and its application to the modelling of tungsten in JET and ASDEX Upgrade
F. J. Casson, C. Angioni, E. A. Belli +13
Recent developments in theory-based modelling of core heavy impurity transport are presented, and shown to be necessary for quantitative description of present experiments in JET a…
