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-…

Microstability of tokamak equilibria

Rahul Gaur, Ian G. Abel, David Dickinson +1

High-power-density tokamaks offer a potential solution to design cost-effective fusion devices. One way to achieve high power density is to operate at a high value (the ratio o…

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…

Extended electron tails in electrostatic microinstabilities and the nonadiabatic response of passing electrons

M. R. Hardman, F. I. Parra, C. Chong +6

Ion-gyroradius-scale microinstabilities typically have a frequency comparable to the ion transit frequency. Due to the small electron-to-ion mass ratio and the large electron trans…
