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

open access: yesNuclear 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.

Reproduction of collector probe deposition profiles using the far-SOL impurity transport code 3DLIM

open access: yesNuclear Materials and Energy, 2020
First results are reported from the 3D Monte Carlo far-SOL impurity transport code 3DLIM. Tungsten deposition profiles measured on a Collector Probe (CP) located in the far-SOL near the outer midplane, OMP, during W tracer experiments in DIII-D are ...

Refining light impurity content estimates at the lower divertor based on experimental data in WEST

open access: yesNuclear Materials and Energy, 2023
WEST is an actively cooled, long-pulse tokamak with nearly all plasma-facing components (PFC) made of tungsten (W). One of the aims of WEST is to study plasma operation with W PFCs in preparation for long-pulse operation on W divertor devices like ITER ...

Anomalous impurity transport in plasmas [PDF]

open access: yesNuclear Fusion, 1983
The transport of hith Z impurities resulting from Compton and induced scattering by drift waves is found to be comparable in magnitude with base ion and electron transport when the fluctuation spectrum is obtained from a recent theory of drift turbulence. The anomalous frictional flux is marginally subdominant whilst the diffusion flux is enhanced over

Stability of divertor detachment

open access: yesNuclear Materials and Energy, 2017
The 2D simulations of edge plasma transport show that unlike some earlier publications, the impurity radiation loss per se does not cause the bifurcation-like transition to detached divertor regime.

The influence of E× B drift on tungsten target erosion and W impurity transport during neon seeding on EAST

open access: yesNuclear Fusion, 2023
Mitigating tungsten (W) wall erosion and core accumulation are vitally important for the steady-state operation of tokamaks. It is well known that drifts have a great impact on the transport of charged particles in the edge region, which could affect W ...

Modeling of Impurity Transport in the Divertor of JET

open access: yesPlasma and Fusion Research, 2013
Deposition/erosion measurements by means of a Quartz Micro Balance (QMB) located below the Load Bearing Septum Replacement Plate in the private flux region of the inner divertor of JET (with full carbon wall) revealed net deposition with the inner strike point located on the vertical tile and net erosion with the inner strike point on the horizontal ...

Preliminary Result of Neoclassical Impurity Transport Affected by ICRH with a 4-D Fokker-Planck Code [PDF]

open access: yesEPJ Web of Conferences
To understand the role of ion cyclotron resonance heating (ICRH) in mitigating tungsten accumulation, we evaluate the impact of ICRH-induced poloidal asymmetries on neoclassical impurity transport using a newly developed 4-D Fokker–Planck code (FP4D ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
