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

Plasma Physics and Controlled Fusion, 2019
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.

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 ...

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.

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 ...

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.

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 ...

First Monte‐Carlo modelling of global beryllium migration in ITER using ERO2.0

Contributions to Plasma Physics, Volume 60, Issue 5-6, June-July 2020., 2020
Abstract ERO2.0 is a recently developed Monte‐Carlo code for modelling global erosion and redeposition in fusion devices. We report here on the code's application to ITER for studying the erosion of the beryllium (Be) first wall armour under burning plasma steady state diverted conditions.

Investigating the impact of the molecular charge-exchange rate on detached SOLPS-ITER simulations

, 2023
Plasma-molecular interactions generate molecular ions which react with the plasma and contribute to detachment through molecular activated recombination (MAR), reducing the ion target flux, and molecular activated dissociation (MAD), both of which create
