Error‐based grid adaptation methods for plasma edge simulations with SOLPS‐ITER

Contributions to Plasma Physics
AbstractOnly recently, plasma edge simulations up to the wall have been enabled with SOLPS‐ITER. This requires dedicated gridding techniques to reconcile grid alignment with the magnetic field and refinement toward the wall as grid quality is primordial to ensure fast and reliable convergence.

Modelling of high-field-side high-density region with the nonlinear MHD code JOREK with kinetic neutrals [PDF]

, 2022
In this contribution, we have presented a benchmark of JOREK-without drifts-with kinetic neutrals against SOLPS-ITER (without drifts) and the development of the HFSHD-region in JOREK simulations with kinetic neutrals for early ITER operation (the PFPO-1 ...

Deuterium retention in co-deposition with lithium in Magnum-PSI: experimental analysis and comparison with SOLPS-ITER

Nuclear Fusion
The vapor-box, a liquid metal design for the divertor, utilizes lithium recirculation through evaporation and condensation. Safety concerns arise from Li-D/T formation and co-deposition on vapor-box walls and the first wall, affecting tritium retention ...

Sensitivity analysis of plasma edge code parameters through algorithmic differentiation

Nuclear Materials and Energy, 2019
Anomalous radial transport coefficients, boundary conditions and reaction rates are among the main sources of uncertainty within plasma edge modeling. In principle, an analysis to determine the sensitivity of code results to changes in uncertain model ...

Impact of ionization and transport on pedestal density structure in DIII-D and Alcator C-Mod

Nuclear Fusion
This paper investigates the role of ionization on the pedestal structure using both measurements and modeling for H-mode plasmas on DIII-D and Alcator C-Mod to enhance our ability to predict pedestal behavior in future pilot plants.

Modelling of tungsten prompt redeposition at the inner wall of ITER during ramp-up

Nuclear Materials and Energy
The prompt redeposition of sputtered tungsten at the inner wall of ITER during current ramp-up has been simulated with the ERO code. Plasma parameters from SOLPS-ITER for a medium-density (with a peak electron density of 4E12 cm−3 at the inner wall) and ...

SOLPS-ITER simulations to study the impact of aspect ratio on edge fueling neutrals in tokamaks

Nuclear Materials and Energy
In this paper, we examine the role of the aspect ratio on the neutral penetration and poloidal distribution for fixed magnetic geometry and plasma profiles using SOLPS-ITER. We start from an H-mode discharge from MAST (Kirk et al., 2012), with its aspect

SOLPS-ITER simulations of the GyM linear plasma device

, 2019
In the context of magnetic confinement fusion research, understanding and controlling plasma-material interaction (PMI) is a key point for the realisation of future fusion device, such as ITER. Since the conditions foreseen in ITER have never been obtained before, there is the need to study PMI in ITER-relevant regimes both numerically and ...

SICAS, a new integrated divertor-SOL-pedestal-core framework for self-consistent modeling of ion and impurity transport in fusion devices

Nuclear Fusion
We present a new framework for core-edge integration studies named SICAS (SOLPS-ITER coupled to ASTRA-STRAHL) which enables high fidelity simulations of the core, edge, and divertor regions encompassing the transport of ions as well as the impurities ...
