Subcritical turbulence in the Mega Ampere Spherical Tokamak

Abstract:

The transport of heat out of tokamak plasmas by turbulence is the dominant mechanism limiting the performance of fusion reactors. Turbulence can be driven by the ion temperature gradient (ITG) and suppressed by toroidal equilibrium scale sheared flows. Numerical simulations attempting to understand, and ultimately reduce, turbulence are crucial for guiding the design and optimisation of future reactors.

In this thesis, we investigate ion-scale turbulence by means of local gyrok...
