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…
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…
Multiple-isotope pellet cycles captured by turbulent transport modelling in the JET tokamak
M. Marin, J. Citrin, L. Garzotti +8
For the first time the pellet cycle of a multiple-isotope plasma is successfully reproduced with reduced turbulent transport modelling, within an integrated simulation framework. F…
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…
Gyrokinetic analysis and simulation of pedestals, to identify the culprits for energy losses using fingerprints
M. Kotschenreuther, X. Liu, D. R. Hatch +14
Fusion performance in tokamaks hinges critically on the efficacy of the Edge Transport Barrier (ETB) at suppressing energy losses. The new concept of fingerprints is introduced to…
Tractable flux-driven temperature, density, and rotation profile evolution with the quasilinear gyrokinetic transport model QuaLiKiz
J Citrin, C Bourdelle, F J Casson +14
Quasilinear turbulent transport models are a successful tool for prediction of core tokamak plasma profiles in many regimes. Their success hinges on the reproduction of local nonli…
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…
Self-consistent simulation of plasma scenarios for ITER using a combination of 1.5D transport codes and free-boundary equilibrium codes
V Parail, R Albanese, R Ambrosino +20
Self-consistent transport simulation of ITER scenarios is a very important tool for the exploration of the operational space and for scenario optimisation. It also provides an asse…
