Stabilization of EMC3-EIRENE for detachment conditions and comparison to SOLPS-ITER

Nuclear Materials and Energy, 2019
Numerical access to cold divertor conditions in tokamaks with EMC3-EIRENE has been proven to be challenging, but is now possible for the first time after a linearization of the electron energy sink term from interaction with neutral gas.

Implementation of a 9-point stencil in SOLPS-ITER and implications for Alcator C-Mod divertor plasma simulations

Nuclear Materials and Energy, 2019
The SOLPS-ITER code suite is used worldwide for plasma edge modeling, the interpretation of experiments, as well as for the design of the ITER divertor. The numerical scheme of the plasma solver of the code, B2.5, is based on the assumption of perfectly ...

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.

SOLPS-ITER modeling of divertor scenarios for EU-DEMO

Nuclear Fusion, 2021
We developed a first single null divertor scenario for EU-DEMO with the SOLPS-ITER code, including all charge states of D, He and Ar in the simulation and kinetic analysis of the neutral gas, but still leaving out drifts. Our results suggest that a partially detached divertor condition can indeed be obtained, with a corresponding peak heat flux on ...
