A spectroscopic inference and SOLPS-ITER comparison of flux-resolved edge plasma parameters in detachment experiments on TCV [PDF]

Nuclear Fusion, 2022
This work presents the use of a collisional-radiative model to infer plasma parameters from 2D emissivities of several deuterium Balmer lines. The emissivities were obtained by MANTIS, an absolutely calibrated, ten-camera imaging polychromator with

SOLPS-ITER modification for impurity transport modelling in the tokamak pedestal region

Nuclear Materials and Energy
Kinetic corrections to SOLPS-ITER fluid equations are made to extend their applicability for description of the neoclassical part of impurity transport to collisionless regimes of the main ions.

Optimization of lithium vapor box divertor evaporator location on NSTX-U using SOLPS-ITER [PDF]

Nuclear Fusion
Commercial fusion reactors will be faced with extremely high divertor target heat fluxes that will require mitigation. Simulations of detachment in an NSTX-U scenario projected to have 92 MW m−2 unmitigated peak target heat flux are presented, which ...

First SOLPS-ITER modelling of an X-point radiator in ITER

Nuclear Fusion
For the first time, an X -point radiating (XPR) regime using neon (Ne) seed impurity has been obtained in ITER modelling with the SOLPS-ITER code, including fluid drifts.

SOLPS-ITER simulations of a CPS-based liquid metal divertor for the EU DEMO: Li vs Sn [PDF]

Nuclear Fusion, 2022
In this work, we study the effect of installing a liquid metal divertor (LMD) using a capillary-porous structure in the EU DEMO tokamak within the same envelope of the baseline solid divertor.

Design of a closed V-shape slot X-divertor to improve divertor detachment and pumping in HL-3 with SOLPS-ITER

Plasma Physics and Controlled Fusion
To improve detachment and neutral density/pressure in the long-leg open X-diverter of Huanliu-3 (HL-3), a Closed V-shaped slot X-diverter (CVXD) is proposed, which integrates an X-diverter magnetic configuration with a closed V-shaped slot diverter ...

SOLPS-ITER simulations of the ITER divertor with improved plasma-facing component geometry

Nuclear Materials and Energy
The ITER divertor design has been guided by SOLPS4.3 plasma boundary code simulations focused on baseline burning conditions at QDT = 10 which compose the majority of the existing ITER divertor scenario database.

Investigating the influence of divertor baffles on nitrogen-seeded detachment in TCV with SOLPS-ITER simulations and TCV experiments

Nuclear Fusion, 2023
Plasma edge simulations with the SOLPS-ITER code are performed to study the influence of divertor baffles on nitrogen-seeded detachment in Tokamak à Configuration Variable (TCV) single-null, L-mode discharges. Scans of nitrogen seeding rate are conducted
