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.

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 ...

Impact of multifold magnetic structure on spectroscopy analysis in Heliotron J based on EMC3‐EIRENE simulation [PDF]
Contributions To Plasma PhysicsAbstract The distribution pattern of the connection length in the divertor region of Heliotron J was calculated by the field line tracing method. A multifold layer structure, characterized by the range of connection length, was revealed to interpret the response of the transport of the lower‐charged impurity ions to the divertor structure.

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 ...

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.

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.

A novel method for treating MAR in EMC3-Eirene, and first applications to W7-X
Nuclear FusionThis paper presents a novel ‘prediction-correction method’ for treating molecule-assisted recombination (MAR) in the three-dimensional (3D) boundary plasma transport code—EMC3-Eirene.
