The programme to design plasma scenarios for the Spherical Tokamak for Energy
Production (STEP), a reactor concept aiming at net electricity production, seeks to exploit the …

Spherical tokamaks have many desirable features that make them an attractive choice for a
future fusion power plant. Power-plant viability is intrinsically related to plasma heat and …

In this work, we present first-of-their-kind nonlinear local gyrokinetic (GK) simulations of
electromagnetic turbulence at mid-radius in the burning plasma phase of the conceptual …

A quasi-linear reduced transport model is developed from a database of high-$\beta $
electromagnetic nonlinear gyrokinetic simulations performed with Spherical Tokamak for …

Fusion energy offers the potential for a near limitless source of low-carbon energy and is
often regarded as a solution for the world's long-term energy needs. To realise such a …

Turbulent transport in magnetically confined fusion plasma has conventionally been
analyzed at the ion gyroradius scale based on the microturbulence theory. However, ion …

Plasma turbulence on disparate spatial and temporal scales plays a key role in defining the
level of confinement achievable in tokamaks, with the development of reduced numerical …

Electromagnetic microtearing modes (MTMs) have been observed in many different
spherical tokamak regimes. Understanding how these and other electromagnetic modes …
