In this paper, we review the thermal plasma confinement and transport properties observed
and predicted in low aspect ratio tokamaks, or spherical tokamaks (STs), which can depart …

The question of size of a tokamak fusion reactor is central to current fusion research
especially with the large device, ITER, under construction and even larger DEMO reactors …

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 …

Abstract Tokamak Energy Ltd, UK, is develo** spherical tokamaks using high temperature
superconductor magnets as a possible route to fusion power using relatively small devices …

Full power operation of the International Thermonuclear Experimental Reactor (ITER) has
been delayed and will now begin in 2035. Delays to the ITER schedule may affect the …

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 …

Abstract The Fusion Nuclear Science Facility (FNSF) is examined here as part of a two step
program from ITER to commercial power plants. This first step is considered mandatory to …

SPARC is being designed to operate with a normalized beta of that rises linearly with a
change in the plasma current. Massive material injection is planned to reduce the disruption …

The work presents the results of the energy confinement study carried out on the compact
spherical tokamak Globus-M2 with a toroidal magnetic field as high as 0.8 T. A reproducible …
