SOLPS-ITER simulations of the TCV divertor upgrade [PDF]

Plasma Physics and Controlled Fusion, 2019
Abstract The effect of the upcoming TCV divertor upgrade on the distribution of neutrals and the onset of detachment is studied using 2D transport code simulations. The divertor upgrade is centered around the installation of a gas baffle to form a divertor chamber of variable closure.

Time-dependent SOLPS-ITER simulations of the tokamak plasma boundary for model predictive control using SINDy

Nuclear Fusion, 2023
Time-dependent SOLPS-ITER simulations have been used to identify reduced models with the sparse identification of nonlinear dynamics (SINDy) method and develop model-predictive control of the boundary plasma state using main ion gas puff actuation.

Combination of micro–macro and spatially hybrid fluid‐kinetic approach for hydrogenic plasma edge neutrals

Contributions to Plasma Physics, Volume 62, Issue 5-6, June‐July 2022., 2022
Abstract A new hybrid fluid‐kinetic approach for the hydrogenic neutrals (atoms and molecules) in the plasma edge is presented. The hybrid approach combines a fully kinetic model for the atoms in the low‐collisional regions near the vessel wall, and for the molecules in the whole plasma edge domain, with a micro–macro approach for atoms originating ...

Implementation of SOLPS-ITER code with new Grad–Zhdanov module for D–T mixture

Nuclear Fusion, 2023
A new Grad–Zhdanov module is implemented into the SOLPS-ITER code for calculation of the parallel kinetic coefficients. A complete, multi-ion generalization is performed, relaxing the heavy impurity assumption.

Impact of vibrationally resolved H2 on particle balance in Eirene simulations

Contributions to Plasma Physics, Volume 62, Issue 5-6, June‐July 2022., 2022
Abstract To evaluate the impact of transport of metastable, vibrationally excited states of the hydrogen molecule in dense and cold plasmas each vibrational state must be simulated as an individual species. Eirene neutral gas simulations of a one‐dimensional flux‐tube using a metastable‐resolved model indicate a 30–50% decrease in the effective ...

The role of edge fueling in determining the pedestal density in high neutral opacity Alcator C-Mod experiments

Nuclear Materials and Energy, 2021
SOLPS-ITER modeling of EDA H-mode experiments on Alcator C-Mod find that the electron density pedestal structure is unaffected by increased gas fueling when approaching ITER-like opaqueness conditions.

Quantification of the uncertainty arising from atomic physics in edge plasmas

Nuclear Materials and Energy, 2022
It is clear that atomic physics rates are important for understanding the edge plasma — but how important is the uncertainty in these rates in contributing to the uncertainty in simulations of the edge plasma?Standard Uncertainty Quantification (UQ ...

SOLPS-ITER modeling of ASDEX Upgrade L-mode detachment states

Plasma Physics and Controlled Fusion, 2021
Abstract SOLPS-ITER is used to model ASDEX Upgrade L-mode detachment states including the onset of detachment, the fluctuating detachment, and the complete detachment states, considering drifts and mimicking filamentary convective transport with a radial outward velocity in the low field side.

SOLPS-ITER modelling of ITER edge plasma with drifts and currents [PDF]

Nuclear Fusion, 2020
Using the new version of the SOLPS plasma boundary code package, SOLPS-ITER, this paper presents the first ever simulations of the ITER burning baseline H-mode edge plasma with drifts and currents activated. Neon (Ne) seeded discharges for divertor power dissipation are considered. The results for divertor and scrape-off layer (SOL) parameters with and

SOLPS-ITER simulation of an X-point radiator in TCV

, 2023
SOLPS-ITER simulation is performed to reproduce the X-point radiator recently observed in nitrogen-seeded TCV experiments, which is a scenario that may be favorable to solve the power exhaust problems in future fusion devices. The simulations reveal the transition from the detached regime without XPR to the XPR regime, when increasing the nitrogen ...
