On the Use of CX Atom Analyzer for Study Characteristics of Ion Component in a LHD Divertor Plasma

, 1996
"In this paper the analysis was provided for the possibility to use the charge exchange atom analyzer using the ion reflection phenomena on solid surtfaces for measuring the characteristics of the ion component of a divertor plasma in LHD. As an ion-atom

Application of two-dimensional temperature response functions for reconstruction of divertor heat flux profile in commercial fusion reactors [PDF]

ORCID　0009-0005-6662-7935To keep the tritium breeding rate TBR > 1 and to meet the high heat load and neutron shielding requirements for the first wall and divertor in fusion demonstration (DEMO) reactors, the number of port plugs and other openings must

Challenges and approaches to interpretive modeling of boundary plasma and neutral transport in a closed, pumped divertor

Nuclear Fusion
An experimental discharge from the DIII-D tokamak is modeled using the SOLPS-ITER code suite and compared against measurements in the pumped and relatively closed upper divertor.

LHD Helical Divertor

, 1993
"The Large Helical Device (LHD) now under construction is a heliotron/torsatron device with a closed divertor system. The edge LHD magnetic structure has been studied in detail. A peculiar feature of the configuration is existence of edge surface layers ,

Divertor plasma conditions and their effect on carbon migration in the ASDEX Upgrade tokamak [PDF]

, 2011
Divertors play a critical role in power and particle exhaust and plasma-material interaction in tokamaks. Of particular concern is the release of impurities from the material components, which reduces the lifetime of the vessel wall and affects the ...

Dependence of divertor turbulence on plasma density and current in TCV

Nuclear Fusion
To reliably predict the distribution of heat and particle fluxes at the target plates of tokamaks, a comprehensive understanding of turbulence throughout the entire Scrape-Off-Layer (SOL) is imperative.

VUV Spectroscopy in DIII-D Divertor

, 2004
The research carried out on this grant was motivated by the high power emission from the CIV doublet at 155 nm in the DIII-D divertor and to study the characteristics of the radiative divertor.

Experiments on plasma detachment in a V-shaped slot divertor in the DIII-D tokamak

Nuclear Fusion
Experiments in DIII-D demonstrate that the upstream plasma density to detach an un-pumped slot divertor is similar for a V-shaped and a flat-end slot, despite significantly higher neutral pressure in the V-shaped slot and in contrast to SOLPS-ITER ...

Introduction to divertor physics

, 2017
A brief review will be given on the physics of divertor, which plays a very important role in magnetic confinement devices. The divertor "diverts" the power and particles coming out from the core plasma to a volume separated from the core.

Control of divertor geometry and performance with the ergodic divertor of Tore Supra

, 2000
Experimental evidence of the location of the ergodic divertor separatrix is shown to agree with the predicted value given by codes. Variation of this position modifies the divertor tightness, defined as the ratio of the divertor to core density.
