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.

Non-linear simulations of the TCV Scrape-Off Layer
Nuclear Materials and Energy, 2017 To investigate the mechanisms leading to the heat deposition onto the first wall in the Scrape-Off Layer (SOL), we perform dedicated numerical non-linear simulations of the SOL plasma dynamics of a TCV discharge using the GBS code. The simulated parallel

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,

On the interaction of scrape off layer filaments [PDF]
Plasma Physics and Controlled Fusion, 2017 The interaction of L-mode and inter-ELM Scrape-Off Layer (SOL) filaments is investigated by simulating the dynamics of two seeded density perturbations with different initial separation. A numerical campaign of 2D and 3D simulations is presented to explore the effect that different filaments’ perpendicular size and relative distance have on their ...

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 ...

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)).

Detached scrape-off layer tokamak plasmas [PDF]
Physics of Plasmas, 1995 The equilibrium and stability of scrape-off layer plasmas are considered using a one-dimensional treatment of coupled heat conduction and pressure balance equations. It is found that, for sufficiently low-temperature and high neutral density, a region of greatly reduced power flux to the endplate can be achieved.

A spectral filament model for turbulent transport and scrape off layer width in circular geometry
Nuclear Materials and Energy, 2019 Radial transport in scrape off layer is commonly attributed to the intermittent convection of plasma filaments. These filaments are observed in experiments, and commonly reproduced by turbulent simulations.

SOL parallel momentum loss in ASDEX Upgrade and comparison with SOLPS
Nuclear Materials and Energy, 2017 An H-mode database of ASDEX Upgrade plasmas with improved diagnostics for a variety of different plasma conditions has been analysed to study the momentum removal in the Scrape-Off Layer (SOL).
