New linear stability parameter to describe low-$\beta$ electromagnetic microinstabilities driven by passing electrons in axisymmetric toroidal geometry

Autor: M R Hardman, F I Parra, B S Patel, C M Roach, J Ruiz Ruiz, M Barnes, D Dickinson, W Dorland, J F Parisi, D St-Onge, H Wilson

In magnetic confinement fusion devices, the ratio of the plasma pressure to the magnetic field energy, $\beta$, can become sufficiently large that electromagnetic microinstabilities become unstable, driving turbulence that distorts or reconnects the

Non-local effects on pedestal kinetic ballooning mode stability

Publikováno v: Plasma Physics and Controlled Fusion

The H-mode pedestal height plays an important role in determining the global confinement of the tokamak plasma. In type I ELMy H-mode the ultimate limit for the pedestal pressure at constant width is set by the ideal MHD peeling-ballooning modes (PBM

Turbulent transport in tokamak plasmas with rotational shear

Autor: Alexander Schekochihin, Felix I. Parra, Steven Cowley, C. M. Roach, Edmund Highcock, Michael Barnes

Nonlinear gyrokinetic simulations have been conducted to investigate turbulent transport in tokamak plasmas with rotational shear. At sufficiently large flow shears, linear instabilities are suppressed, but transiently growing modes drive subcritical
