EMC3-Eirene simulations of the tungsten injection experiments in Tore Supra [PDF]

Journal of Nuclear Materials, 2013
Abstract We report on the first full 3D EMC3-Eirene simulations of the bulk plasma, neutral gas and W impurity transport in Tore Supra (TS). Three configurations are addressed: (A) the high field side-, (B) bottom- and (C) low field side limited case and compared to Mach probe measurements at the top of the device.

3D global impurity transport modeling with WallDYN and EMC3-Eirene

Nuclear Materials and Energy, 2018
The global impurity migration code WallDYN was coupled to the 3D scrape off layer plasma solver EMC3-Eirene in order to make WallDYN applicable to 3D, non-toroidally symmetric, geometries.

TCV divertor upgrade for alternative magnetic configurations [PDF]

Nuclear Materials and Energy, 2017
The Swiss Plasma Center (SPC) is planning a divertor upgrade for the TCV tokamak. The upgrade aims at extending the research of conventional and alternative divertor configurations to operational scenarios and divertor regimes of greater relevance for a ...

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 the 3D edge plasma code EMC3-EIRENE on NSTX [PDF]

Nuclear Fusion, 2012
The 3D edge transport code EMC3-EIRENE has been applied for the first time to the NSTX spherical tokamak. A new disconnected double null grid has been developed to allow the simulation of plasma where the radial separation of the inner and outer separatrix is less than characteristic widths (e.g. heat flux width) at the midplane.

Proposal of an alternative upper divertor in ASDEX Upgrade supported by EMC3-EIRENE simulations

Nuclear Materials and Energy, 2017
We discuss the benefits of installing a pair of in-vessel coils with currents |Ifx| ≲ 50 kAt in the upper divertor of ASDEX Upgrade (AUG) to study a series of ‘alternative’ divertor configurations, like the Snowflake (SF) and the X-divertor (XD), that ...

EMC3-EIRENE modeling of toroidally-localized divertor gas injection experiments on Alcator C-Mod [PDF]

Journal of Nuclear Materials, 2015
Abstract Experiments on Alcator C-Mod with toroidally and poloidally localized divertor nitrogen injection have been modeled using the three-dimensional edge transport code EMC3-EIRENE to elucidate the mechanisms driving measured toroidal asymmetries.

Study of detachment in future ASDEX Upgrade alternative divertor configurations by means of EMC3-EIRENE [PDF]

Nuclear Materials and Energy, 2021
ASDEX Upgrade is preparing a hardware modification of its upper divertor in order to study alternative divertor configurations, like the X-divertor (XD) and the snowflake divertor (SF), that are discussed as a possible solution for the power exhaust ...
