shear suppression of microtearing based transport in spherical tokamaks
B. S. Patel, M. R. Hardman, D. Kennedy +3
Electromagnetic microtearing modes (MTMs) have been observed in many different spherical tokamak regimes. Understanding how these and other electromagnetic modes nonlinearly satura…
Flat-top plasma operational space of the STEP power plant
E. Tholerus, F. J. Casson, S. P. Marsden +16
STEP is a spherical tokamak prototype power plant that is being designed to demonstrate net electric power. The design phase involves the exploitation of plasma models to optimise…
Electromagnetic gyrokinetic instabilities in STEP
Daniel Kennedy, Maurizio Giacomin, Francis J Casson +4
We present herein the results of a linear gyrokinetic analysis of electromagnetic microinstabilites in the conceptual high-, reactor-scale, tight-aspect-ratio tokamak STEP (Sphe…
On electromagnetic turbulence and transport in STEP
Maurizio Giacomin, Daniel Kennedy, Francis J Casson +4
In this work, we present first-of-their-kind nonlinear local gyrokinetic simulations of electromagnetic turbulence at mid-radius in the burning plasma phase of the conceptual high-…
Three-Dimensional Inhomogeneity of Electron-Temperature-Gradient Turbulence in the Edge of Tokamak Plasmas
J. F. Parisi, F. I. Parra, C. M. Roach +15
Nonlinear multiscale gyrokinetic simulations of a Joint European Torus edge pedestal are used to show that electron-temperature-gradient (ETG) turbulence has a rich three-dimension…
Linear gyrokinetic stability of a high non-inductive spherical tokamak
B. S. Patel, D. Dickinson, C. M. Roach +1
Spherical tokamaks (STs) have been shown to possess properties desirable for a fusion power plant such as achieving high plasma ? and having increased vertical stability. To unders…
