Access and sustainment of ELMy H-mode operation for ITER Pre-Fusion Power Operation plasmas using JINTRAC
E. Tholerus, L. Garzotti, V. Parail +15
In the initial stages of ITER operation, ELM mitigation systems need to be commissioned. This requires controlled flat-top operation in type-I ELMy H-mode regimes. Hydrogen or heli…
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…
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…
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…
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…
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…
Pellet refuelling of particle loss due to ELM mitigation with RMPs in the ASDEX Upgrade tokamak at low collisionality
M Valovič, P T Lang, A Kirk +17
The complete refuelling of the plasma density loss (pump-out) caused by mitigation of Edge Localised Modes (ELMs) is demonstrated on the ASDEX Upgrade tokamak. The plasma is refuel…
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…
Characterisation of the L-mode Scrape Off Layer in MAST: decay lengths
F. Militello, L. Garzotti, J. Harrison +7
This work presents a detailed characterisation of the MAST Scrape Off Layer in L-mode. Scans in line averaged density, plasma current and toroidal magnetic field were performed. A…
Core micro-instability analysis of JET hybrid and baseline discharges with carbon wall
S. Moradi, I. Pusztai, I. Voitsekhovitch +6
The core micro-instability characteristics of hybrid and baseline plasmas in a selected set of JET plasmas with carbon wall are investigated through local linear and non-linear and…
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…
Pellet fuelling with edge-localised modes controlled by external magnetic perturbations in MAST
M Valovic, L Garzotti, C Gurl +6
The fuelling of plasmas by shallow frozen pellets with simultaneous mitigation of edge localised modes (ELM) by external magnetic perturbation is demonstrated on the MAST tokamak.…
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…
Microstability analysis of pellet fuelled discharges in MAST
L. Garzotti, J. Figueiredo, C. M. Roach +7
Reactor grade plasmas are likely to be fuelled by pellet injection. This technique transiently perturbs the profiles, driving the density profile hollow and flattening the edge tem…
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…
