In this paper, the theory of collisional and turbulent transport of impurities in tokamak
plasmas is reviewed. The results are presented with the aim of providing at the same time a …

Neoclassical transport processes are important to the understanding of plasma confinement
physics in doubly periodic magnetized toroidal plasmas, especially, after the impact of the …

Abstract The Chinese Fusion Engineering Testing Reactor (CFETR), complementing the
ITER facility, is aiming to demonstrate fusion energy production up to 200 MW initially and to …

Edge-localized-modes (ELMs) are a ubiquitous feature of H-mode in tokamaks. When
gradients in the H-mode transport barrier grow to exceed the MHD stability limit the ELM …

We describe a new approach to solve the electromagnetic gyrokinetic equations which is
optimized for accurate treatment of multispecies Fokker–Planck collisions including both …

, Nucl. Fusion 39, 2137 (1999)] remains an important challenge. While uncertainties remain,
magnetohydrodynamic stability calculations at intermediate wavelength (the “peeling …

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 …

The behaviour of tungsten in the core of hybrid scenario plasmas in JET with the ITER-like
wall is analysed and modelled with a combination of neoclassical and gyrokinetic codes. In …

Quasi-symmetry can greatly improve the confinement of energetic particles and thermal
plasma in a stellarator. The magnetic field of a quasi-symmetric stellarator at high plasma …

Fusion whole device modeling simulations require comprehensive models that are
simultaneously physically accurate, fast, robust, and predictive. In this paper we describe the …
