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 …

Stellarator magnetic configurations need to be optimized in order to meet all the required
properties of a fusion reactor. In this work, it is shown that a flat-mirror quasi-isodynamic (QI) …

The current state of the EUTERPE code is described with emphasis on the implemented
models and their numerical implementation. The code solves the multi-species …

The influence of rotation, collisionality and trapped particle fraction on the magnitude and
direction of neoclassical impurity transport in tokamaks is analyzed using an extensive …

Particle pump-out effects induced by low-frequency (< 200 kHz) density fluctuations were
observed in solely electron cyclotron wave (ECW)-heated plasmas on the spherical torus …

A study of turbulent impurity transport by means of quasilinear and nonlinear gyrokinetic
simulations is presented for Wendelstein 7-X (W7-X). The calculations have been carried out …

Laser blow-off injections of aluminum and tungsten have been performed on the DIII-D
tokamak to investigate the variation of impurity transport in a set of dedicated ion and …

A good understanding of the confinement of energetic ions in non-axisymmetric magnetic
fields is key for the design of reactors based on the stellarator concept. In this work, we …

Flux-surface variations of the electrostatic potential are typically neglected in standard
neoclassical theory, but in 3D devices they can be large enough to affect the radial particle …

Abstract KNOSOS (KiNetic Orbit-averaging SOlver for Stellarators) is a freely available, open-
source code (https://github. com/joseluisvelasco/KNOSOS) that calculates neoclassical …
