Plasma edge modelling with ICRF coupling

EPJ Web of Conferences, 2017
The physics of Radio-Frequency (RF) wave heating in the Ion Cyclotron Range of Frequencies (ICRF) in the core plasmas of fusion devices are relatively well understood while those in the Scrape-Off Layer (SOL) remain still unresolved.

Self‐consistent transport simulation of boron dust particle injection in the peripheral plasma in Large Helical Device

Contributions to Plasma Physics, Volume 64, Issue 7-8, August-September 2024.
Abstract The trajectories and the ablation positions of boron dust particles dropped from an impurity powder dropper in the peripheral plasma in the Large Helical Device (LHD) were calculated using a three‐dimensional edge plasma simulation code (EMC3‐EIRENE) and a dust transport simulation code (DUSTT).

Toward plasma drifts in EMC3: Implementation of gradient, divergence, and particle tracing schemes

Contributions to Plasma Physics, Volume 64, Issue 7-8, August-September 2024.
Abstract This paper presents a first implementation of gradient, divergence, and particle tracing schemes for the EMC3 code, a stochastic 3D plasma fluid code widely employed for edge plasma and impurity transport modeling in tokamaks and stellarators.

Modeling the toroidal asymmetry of the heat load impacted by nitrogen injection in EAST using EMC3-EIRENE

Plasma Physics and Controlled Fusion, 2021
Abstract The effects of nitrogen injection on the heat load in the scape-off layer are systematically investigated in the EAST double-null divertor configuration using EMC3-EIRENE code. Nitrogen impurities injected near the separatrix line and away from the separatrix line give rise to a non-axisymmetric distribution of heat load on ...

Modeling of plasma beta effects on the island divertor transport in the standard configuration of W7-X

Nuclear Fusion, 2023
The influence of plasma beta effects on the edge plasma transport in the Wendelstein 7-X standard configuration is studied systematically by using EMC3-EIRENE combined with a 3D equilibrium code named HINT. The magnetic topology changes induced by plasma
