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…
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,…
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 - Construction Status
Joe Milnes, Nizar Ben Ayed, Fahim Dhalla +8
The Mega Amp Spherical Tokamak (MAST) is the centre piece of the UK fusion research programme. In 2010, a MAST Upgrade programme was initiated with three primary objectives, to con…
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…
Investigation of conventional and Super-X divertor configurations of MAST Upgrade using SOLPS
E Havlickova, W Fundamenski, M Wischmeier +2
One of the first studies of MAST Upgrade divertor configurations with SOLPS5.0 are presented. We focus on understanding main prospects associated with the novel geometry of the Sup…
Power Deposition on Tokamak Plasma-Facing Components
Wayne Arter, Valeria Riccardo, Geoff Fishpool
The SMARDDA software library is used to model plasma interaction with complex engineered surfaces. A simple flux-tube model of power deposition necessitates the following of magnet…
L-Mode and Inter-ELM Divertor Particle and Heat Flux Width Scaling on MAST
J. R. Harrison, G. M. Fishpool, A. Kirk
The distribution of particles and power to plasma-facing components is of key importance in the design of next-generation fusion devices. Power and particle decay lengths have been…
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…
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…
Benchmarking of a 1D Scrape-off layer code SOLF1D with SOLPS and its use in modelling long-legged divertors
E Havlickova, W Fundamenski, F Subba +3
A 1D code modelling SOL transport parallel to the magnetic field (SOLF1D) is benchmarked with 2D simulations of MAST-U SOL performed via the SOLPS code for two different collisiona…
