Probe measurements in the scrape-off layer of a Tokamak

Plasma Physics, 1978
A Langmuir probe is used to study the plasma behaviour in the scrape-off layer of JFT-2a, (a Tokamak with an axisymmetric divertor). The measurements reveal particle fluxes to the divertor and the wall as well as cross-field profiles of density and potential in the scrape-off layer.

Structure of the classical scrape-off layer of a tokamak

Plasma Physics and Controlled Fusion, 2018
Abstract The structure of the scrape-off layer (SOL) of a tokamak with little or no turbulent transport is analyzed. The analytical estimates of the density and electron temperature fall-off lengths of the SOL are put forward.

Scrape-off layer and divertor physics

Nuclear Fusion
Since the publication of the review Progress in the ITER Physics Basis (PIPB) in 2007, significant progress has been made in understanding the processes at the plasma-material interface. This review, part of the ITPA Nuclear Fusion Special Issue On the Path to Burning Plasma Operation, presents these developments, focusing on key areas such as the ...

Influence of scrape-off layer on plasma confinement

Physics of Plasmas, 2011
The purpose of this paper is to discuss how plasma phenomena in the scrape-off layer (SOL) can affect the plasma density gradient at the separatrix and hence the plasma behavior inside the separatrix. The parallel flow loss rate and ionization rate in the SOL (related to the electron temperature and neutral gas density) affect the curvature of the ...

Convective transport in the scrape-off layer of tokamaks

Physics of Plasmas, 2005
A detailed study of blob formation, dynamics, and the associated convective transport in the scrape-off layer (SOL) of tokamak plasmas is presented. Dissipation level in the system, in addition to the blob size, is shown to play an important role in determining whether a blob propagates as a coherent object.

Scrape-off layers in which ionisation is important

Journal of Nuclear Materials, 1984
Abstract Ionisation occuring in the scrape-off region of magnetically-confined plasmas can result in significant changes in the density profile. An analytic model is presented and results are compared with a computer model result for INTOR. Sub-layers are identified in the scrape-off layer, including a density plateau, and criteria for the existence ...
