Fusion energy offers the potential for a near limitless source of low-carbon energy and is oftenregarded as a solution for the world’s long-term energy needs. To realise such a scenario requiresthe design of high-performance fusion reactors capable of maintaining the extreme conditionsnecessary to enable fusion. Turbulence …

A new quasilinear saturation model SAT3 has been developed for the purpose of calculating radial turbulent fluxes in the core of tokamak plasmas. The new model is shown to be able to better recreate the isotope mass dependence of nonlinear gyrokinetic fluxes compared to contemporary quasilinear models, including SAT2 [1], whilst performing at least…

The verification and calibration of a new quasi-linear transport model with a large database of gyrokinetic turbulence simulations is presented in this paper. In a previous paper [1], a model for the saturated spectrum of electric potential fluctuations was developed based on the properties of the non-linear 3D spectrum. In this paper, a modificat…
