The effect of gas injection location on a lithium vapor box divertor in NSTX-U

Nuclear Fusion, 2023
The lithium vapor box divertor is a proposed divertor design that will minimize contamination of the upstream plasma in a fusion device, while also ensuring protection of the target.

Investigation of the Helical Divertor Function and the Future Plan of a Closed Divertor for Efficient Particle Control in the LHD Plasma Periphery

, 2009
The function of the divertor plasmas on the particle control in the plasma periphery is investigated from viewpoints of magnetic field line structures and neutral particle transport in the Large Helical Device (LHD).

The effects of gas puff locations and divertor closure on detachment conditions in MAST-U

Nuclear Fusion
The effect of different D _2 fueling locations and divertor closure on MAST-U is studied in detail with the SOLPS-ITER code to gain insights into detachment physics of H-mode plasma experiments in conventional divertor configuration.

Impact of divertor closure on power exhaust in negative triangularity in TCV

Nuclear Fusion
Negative triangularity (NT) is a promising edge-localized mode-free candidate for future fusion reactors. In this paper, the impact of increased divertor closure on density-ramp induced detachment in NT is assessed in the Tokamak á configuration variable

Misalignment of magnetic field in DIII-D assessed by post-mortem analysis of divertor targets

Nuclear Fusion, 2022
We assess the toroidal magnetic field B _t asymmetry in DIII-D due to a misalignment of the toroidal field coils with respect to the poloidal magnetic field coils and vacuum vessel.

Comparison of 2D simulations of detached divertor plasmas with divertor Thomson measurements in the DIII-D tokamak

Nuclear Materials and Energy, 2017
A modeling study is reported using new 2D data from DIII-D tokamak divertor plasmas and improved 2D transport model that includes large cross-field drifts for the numerically difficult low anomalous transport regime associated with the H-mode.

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.

MAST Upgrade Divertor Facility: A Test Bed for Novel Divertor Solutions [PDF]

IEEE Transactions on Plasma Science, 2018
The challenge of integrated exhaust consistent with the other requirements in DEMO and power plant class tokamaks (ITER-like and alternative DEMOs, Fusion Nuclear Science Facility approaches) is well-known and the exhaust solution is likely to be fundamental to the design and operating scenarios chosen.
