Micro-tearing modes in the Mega Ampere Spherical Tokamak
D J Applegate, C M Roach, J W Connor +4
Recent gyrokinetic stability calculations have revealed that the spherical tokamak is susceptible to tearing parity instabilities with length scales of a few ion Larmor radii perpe…
Kinetic instabilities that limit β in the edge of a tokamak plasma: a picture of an H-mode pedestal
D. Dickinson, C. M. Roach, S. Saarelma +3
Plasma equilibria reconstructed from the Mega-Amp Spherical Tokamak (MAST) have sufficient resolution to capture plasma evolution during the short period between edge-localized mod…
Towards the construction of a model to describe the inter-ELM evolution of the pedestal on MAST
D. Dickinson, S. Saarelma, R. Scannell +3
Pedestal profiles that span the ELM cycle have been obtained and used to test the idea that the pedestal pressure gradient in MAST is limited by the onset of Kinetic Ballooning Mod…
Transport Bifurcation Induced by Sheared Toroidal Flow in Tokamak Plasmas
E. G. Highcock, M. Barnes, F. I. Parra +3
First-principles numerical simulations are used to describe a transport bifurcation in a differentially rotating tokamak plasma. Such a bifurcation is more probable in a region of…
