This review is devoted to tokamak plasmas with a cross sectional shape featuring negative
triangularity, which appear to hold great promise as a candidate reactor configuration owing …

Nuclear fusion is one of the most attractive alternatives to carbon-dependent energy
sources. Harnessing energy from nuclear fusion in a large reactor scale, however, still …

The high poloidal-beta (β P) regime was first proposed as a high bootstrap current scenario
for a steady-state fusion pilot plant (FPP) in the 1990s (Kikuchi in Nucl Fusion 30: 265 …

The SPARC tokamak project, currently in engineering design, aims to achieve breakeven
and burning plasma conditions in a compact device, thanks to new developments in high …

Plasma discharges with a negative triangularity (δ=-0.4) shape have been created in the DIII-
D tokamak with a significant normalized beta (β N= 2.7) and confinement characteristic of …

Divertor detachment offers a promising solution to the challenge of plasma-wall interactions
for steady-state operation of fusion reactors. Here, we demonstrate the excellent …

Multi-channel, nonlinear predictions of core temperature and density profiles are performed
for the SPARC tokamak (Creely et al 2020 J. Plasma Phys. 86 865860502) accounting for …

In recent years tokamak experiments and modelling have increasingly indicated that the
interaction between suprathermal (fast) ions and thermal plasma can lead to a reduction of …

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 …

SPARC is designed to be a high-field, medium-size tokamak aimed at achieving net energy
gain with ion cyclotron range-of-frequencies (ICRF) as its primary auxiliary heating …
