Quantification of locked mode instability triggered by a change in confinement

M. Peterka, J. Seidl, T. Markovic +24

This work presents the first analysis of the disruptive locked mode (LM) triggered by the dynamics of a confinement change. It shows that, under certain conditions, the LM threshol…

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…

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…

ELM mitigation via rotating resonant magnetic perturbations on MAST

A. J. Thornton, A. Kirk, P. Cahyna +7

The application of resonant magnetic perturbations (RMPs) produces splitting of the divertor strike point due to the interaction of the RMP field and the plasma field. The applicat…

Characteristics of X-point Lobe Structures in Single-Null Discharges on MAST

J. R. Harrison, A. Kirk, I. T. Chapman +4

Lobe structures due to the application of resonant magnetic perturbations (RMPs) have been observed using wide-angle imaging of light from He1+ ions in the vicinity of the lower X-…

The effect of resonant magnetic perturbations on the divertor heat and particle fluxes in MAST

A. J. Thornton, A. Kirk, P. Cahyna +4

Edge localised modes (ELMs) are a concern for future devices, such as ITER, due to the large transient heat loads they generate on the divertor surfaces which could limit the opera…

Understanding ELM mitigation by resonant magnetic perturbations on MAST

A. Kirk, I. T. Chapman, Yueqiang Liu +11

Sustained ELM mitigation has been achieved using RMPs with a toroidal mode number of n=4 and n=6 in lower single null and with n=3 in connected double null plasmas on MAST. The ELM…
