Global scaling of the heat transport in fusion plasmas
Sara Moradi, Johan Anderson, Michele Romanelli +2
A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…
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…
Phase mixing vs. nonlinear advection in drift-kinetic plasma turbulence
A. A. Schekochihin, J. T. Parker, E. G. Highcock +3
A scaling theory of long-wavelength electrostatic turbulence in a magnetised, weakly collisional plasma (e.g., ITG turbulence) is proposed, with account taken both of the nonlinear…
Validating modelling assumptions of alpha particles in electrostatic turbulence
George Wilkie, Ian Abel, Edmund Highcock +1
To rigorously model fast ions in fusion plasmas, a non-Maxwellian equilibrium distribution must be used. In the work, the response of high-energy alpha particles to electrostatic t…
The Zero Turbulence Manifold in Fusion Plasmas
E. G. Highcock
The transport of heat that results from turbulence is a major factor limiting the temperature gradient, and thus the performance, of fusion devices. We use nonlinear simulations to…
Zero-Turbulence Manifold in a Toroidal Plasma
E. G. Highcock, A. A. Schekochihin, S. C. Cowley +4
Sheared toroidal flows can cause bifurcations to zero-turbulent-transport states in tokamak plasmas. The maximum temperature gradients that can be reached are limited by subcritica…
