The diffusion limit of ballistic transport in the scrape-off layer [PDF]

, 2020
At least the far scrape-off layer of magnetically confined fusion plasmas transport is intermittent and non-diffusive as observed by the appearance of plasma filaments.

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 ...

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.

Reduced physics model of the tokamak Scrape-Off-Layer for pulse design

Nuclear Materials and Energy, 2023
The dynamic interplay between the core and the edge plasma has important consequences in the confinement and heating of fusion plasma. The transport of the Scrape-Off-Layer (SOL) plasma imposes boundary conditions on the core plasma, and neutral ...

On the Turbulent Behavior of a Magnetically Confined Plasma near the X-Point

Fluids, 2022
We construct a model for the turbulence near the X-point of a Tokamak device and, under suitable assumptions, we arrive to a closed equation for the electric field potential fluctuations.

Scaling laws for electron kinetic effects in tokamak scrape-off layer plasmas

Nuclear Fusion, 2023
Tokamak edge (scrape-off layer (SOL)) plasmas can exhibit non-local transport in the direction parallel to the magnetic field due to steep temperature gradients.

Divertor erosion at ASDEX Upgrade during helium plasma operations

Nuclear Materials and Energy
The effect of helium plasma operation on the erosion of plasma-facing components at the low-field side divertor of ASDEX Upgrade was investigated during the 2022 helium experimental campaign. A set of tungsten-covered graphite samples with small platinum

Ideal ballooning modes in the tokamak scrape-off layer [PDF]

, 2013
A drift-reduced Braginskii fluid model is used to carry out a linear and non-linear study of ideal ballooning modes in the tokamak scrape-off layer. First, it is shown that the scrape-off layer finite connection length and boundary conditions modify the ...

Detachment scalings derived from 1D scrape-off-layer simulations

Nuclear Materials and Energy
Fusion power plants will require detachment to mitigate sputtering and keep divertor heat fluxes at tolerable levels. Controlling detachment on these devices may require the use of real-time scrape-off-layer modeling to complement the limited set of ...
