Impact of multifold magnetic structure on spectroscopyanalysis in Heliotron J based on EMC3-EIRENE simulation

Contributions to Plasma Physics
AbstractThe 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.

Modeling non-axisymmetry in the DIII-D small angle slot divertor using EMC3-EIRENE

Nuclear Materials and Energy, 2018
The 3D edge transport code EMC3-EIRENE is used to evaluate the effects of non-axisymmetric misalignment of the small angle slot (SAS) divertor on DIII-D.

Full-torus impurity transport simulation in boron powder injection experiments in the Large Helical Device [PDF]

Nuclear Materials and Energy
The toroidal distribution of boron deposition on plasma-facing components (PFCs) in boron powder injection using an impurity power dropper (IPD) was investigated by full-torus simulation and observations in a systematic plasma density-scan experiment ...

Numerical accuracy and convergence with EMC3-EIRENE [PDF]

Plasma Science and Technology, 2020
The iterative Monte Carlo (MC) code EMC3-EIRENE is frequently used for plasma edge simulations in 3D applications. So far, a quantitative evaluation of the numerical quality of the code results remains an open issue. In this paper, we demonstrate a framework for the practical assessment of accuracy and convergence with EMC3-EIRENE. Moreover, we provide

Impact of vibrationally resolved H2 on particle balance in Eirene simulations

Contributions to Plasma Physics, Volume 62, Issue 5-6, June‐July 2022., 2022
Abstract To evaluate the impact of transport of metastable, vibrationally excited states of the hydrogen molecule in dense and cold plasmas each vibrational state must be simulated as an individual species. Eirene neutral gas simulations of a one‐dimensional flux‐tube using a metastable‐resolved model indicate a 30–50% decrease in the effective ...

First EMC3-Eirene simulations of the TCV snowflake divertor [PDF]

Plasma Physics and Controlled Fusion, 2014
One of the approaches to solve the heat load problem in a divertor tokamak is the so called 'snowflake' (SF) configuration, a magnetic equilibrium with two nearby x-points and two additional divertor legs. Here we report on the first EMC3-Eirene simulations of plasma-and neutral particle transport in the scrape-off layer of a series of TCV SF ...

3D simulations of gas puff effects on edge density and ICRF coupling in ASDEX Upgrade [PDF]

, 2016
In recent experiments, a local gas puff was found to be an effective way to tailor the scrape-off layer (SOL) density and improve the ion cyclotron range of frequency (ICRF) power coupling in tokamaks.

Synthetic plasma edge diagnostics for EMC3-EIRENE, highlighted for Wendelstein 7-X [PDF]

Review of Scientific Instruments, 2016
Interpretation of spectroscopic measurements in the edge region of high-temperature plasmas can be a challenge since line of sight integration effects make direct interpretation in terms of quantitative, local emission strengths often impossible. The EMC3-EIRENE code—a 3D fluid edge plasma and kinetic neutral gas transport code—is a suitable tool for ...
