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…
Scrape-off layer ion temperature measurements at the divertor target during type III and type I ELMs in MAST measured by RFEA
S. Elmore, S. Y. Allan, G. Fishpool +4
In future nuclear fusion reactors high heat load events, such as edge-localised modes (ELMs), can potentially damage divertor materials and release impurities into the main plasma,…
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…
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…
Numerical investigation of isolated filament motion in a realistic tokamak geometry
N. R. Walkden, B. D. Dudson, L. Easy +2
This paper presents a numerical investigation of isolated filament dynamics in a simulation geometry representative of the scrape-off layer (SOL) of the Mega Amp Spherical Tokamak…
MAST-Upgrade Divertor Facility and Assessing Performance of Long-Legged Divertors
G. Fishpool, J. Canik, G. Cunningham +7
A potentially important feature in a divertor design for a high-power tokamak is an extended and expanded divertor leg. The upgrade to MAST will allow a wide range of such divertor…
