Bi-directional Alfvén Cyclotron Instabilities in the Mega-Amp Spherical Tokamak
S. E. Sharapov, M. K. Lilley, R. Akers +6
Alfvén cyclotron instabilities excited by velocity gradients of energetic beam ions were investigated in MAST experiments with super-Alfvénic NBI over a wide range of toroidal magn…
Measurement, correction and implications of the intrinsic error fields on MAST
A. Kirk, Yueqiang Liu, R. Martin +3
The misalignment of field coils in tokamaks can lead to toroidal asymmetries in the magnetic field, which are known as intrinsic error fields. These error fields often lead to the…
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…
Pellet fuelling of plasmas with ELM mitigation by resonant magnetic perturbations in MAST
M Valovic, G Cunningham, L Garzotti +6
Shallow fuelling pellets are injected from the high field side into plasmas in which ELMs have been mitigated using external magnetic perturbation coils. The data are compared with…
