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…
L-mode filament characteristics on MAST as a function of plasma current measured using visible imaging
A. Kirk, A. J. Thornton, J. R. Harrison +2
Clear filamentary structures are observed at the edge of tokamak plasmas. These filaments are ejected out radially and carry plasma in the far Scrape Off Layer (SOL) region, where…
Electron and ion heating characteristics during magnetic reconnection in MAST
H. Tanabe, T. Yamada, T. Watanabe +16
Local electron and ion heating characteristics during merging reconnection startup on the MAST spherical tokamak have been revealed for the first time using a 130 channel YAG-TS sy…
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…
Profile measurements in the plasma edge of MAST using a ball pen probe
N. R. Walkden, J. Adamek, S. Allan +6
The ball pen probe (BPP) technique is used successfully to make profile measurements of plasma potential, electron temperature and radial electric field on the Mega Amp Spherical T…
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…
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…
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…
