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…
Unified theory of the semi-collisional tearing mode and internal kink mode in a hot tokamak: implications for sawtooth modelling
J. W. Connor, R. J. Hastie, A. Zocco
In large hot tokamaks like JET, the width of the reconnecting layer for resistive modes is determined by semi-collisional electron dynamics and is much less than the ion Larmor rad…
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…
Scaling of spontaneous rotation with temperature and plasma current in tokamaks
F. I. Parra, M. F. F. Nave, A. A. Schekochihin +6
Using theoretical arguments, a simple scaling law for the size of the intrinsic rotation observed in tokamaks in the absence of momentum injection is found: the velocity generated…
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…
