Fourier Neural Operator for Plasma Modelling
Vignesh Gopakumar, Stanislas Pamela, Lorenzo Zanisi +3
Predicting plasma evolution within a Tokamak is crucial to building a sustainable fusion reactor. Whether in the simulation space or within the experimental domain, the capability…
Filamentary plasma eruptions and the heating and acceleration of electrons
Heinz Isliker, Andres Cathey, Matthias Hoelzl +2
We present test-particle simulations of electrons during a nonlinear MHD simulation of a type-I edge localized mode (ELM) to explore the effect of an eruptive plasma filament on th…
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…
Modelling of spatial structure of divertor footprints caused by edge-localized modes mitigated by magnetic perturbations
Pavel Cahyna, Marina Becoulet, Guido T. A. Huijsmans +7
Resonant magnetic perturbations (RMPs) can mitigate the edge-localized modes (ELMs), i.e. cause a change of the ELM character towards smaller energy loss and higher frequency. Duri…
Effect of resonant magnetic perturbations on low collisionality discharges in MAST and a comparison with ASDEX Upgrade
A. Kirk, W. Suttrop, Yueqiang Liu +19
Sustained ELM mitigation has been achieved on MAST and AUG using RMPs with a range of toroidal mode numbers over a wide region of low to medium collisionality discharges. The ELM e…
Electron kinetics inferred from observations of microwave bursts during edge localised modes in the Mega-Amp Spherical Tokamak
S. J. Freethy, K. G. McClements, S. C. Chapman +5
Recent measurements of microwave and X-ray emission during edge localised mode (ELM) activity in tokamak plasmas provide a fresh perspective on ELM physics. It is evident that elec…
Current understanding of the processes underlying the triggering of and energy loss associated with type I ELMs
A. Kirk, D. Dunai, M. Dunne +7
The type I ELMy H-mode is the baseline operating scenario for ITER. While it is known that the type I ELM ultimately results from the peeling-ballooning instability, there is growi…
Towards understanding edge localised mode mitigation by resonant magnetic perturbations in MAST
I. T. Chapman, A. Kirk, C. J. Ham +10
Type-I Edge Localised Modes (ELMs) have been mitigated in MAST through the application of n = 3, 4 and 6 resonant magnetic perturbations (RMPs). For each toroidal mode number of th…
