Currents structure in the scrape-off layer of a tokamak

Nuclear Materials and Energy, 2020
Currents structure in the scrape-off layer (SOL) of a tokamak is analyzed. It is demonstrated that poloidal currents measured in the experiments are a combination of several current types of different physical nature.

Effects of drifts on scrape-off layer transport in W7-X

Nuclear Fusion, 2023
Drifts affect particle, momentum, and energy transport in the scrape-off layer (SOL) of tokamaks and stellarators, altering plasma flows and creating asymmetries between divertors. To understand how drifts affect SOL transport in the W7-X island divertor,

Application of a two-fluid two-point model to SolEdge2D-EIRENE simulations of TCV H-mode plasma

Nuclear Materials and Energy, 2019
The edge and scrape-off layer (SOL) plasma of the inter-ELM phase of an H-mode discharge from the TCV tokamak is modeled with the transport code SolEdge2D-EIRENE (Bufferand et al. Nuclear Fusion 55 (2015)).

Scrape off layer profiles interpreted with filament dynamics [PDF]

Nuclear Fusion, 2016
Abstract A theoretical framework is developed to link the density profiles in the scrape off layer (SOL) with the fluctuations (filaments) that generate them. The framework is based on the dynamics of independent filaments and their statistical behaviour and can be used to rigorously understand the mechanisms that lead to flattening and ...

Plasma turbulence in the scrape-off layer of the ISTTOK tokamak [PDF]

Physics of Plasmas, 2016
The properties of plasma turbulence in a poloidally limited scrape-off layer (SOL) are addressed, with focus on ISTTOK, a large aspect ratio tokamak with a circular cross section. Theoretical investigations based on the drift-reduced Braginskii equations are carried out through linear calculations and non-linear simulations, in two- and three ...

Computations of Intermittent Transport in Scrape-Off Layer Plasmas [PDF]

Physical Review Letters, 2004
Two-dimensional fluid simulations of interchange turbulence for geometry and parameters relevant for the scrape-off layer of magnetized plasmas are presented. The computations, which have distinct plasma production and loss regions, reveal bursty ejection of particles and heat from the bulk plasma in the form of blobs.

Transient analysis of high-Z impurity screening by additional injection of low-Z impurity using integrated divertor code SONIC

Nuclear Fusion, 2023
The dynamics of the screening effect of Ar impurity by the injection of additional Ne has been studied through time-dependent analysis with the integrated divertor code SONIC. In the preceding study (Yamoto et al 2020 Plasma Phys. Control.
