Anomalous impurity transport in plasmas [PDF]
Nuclear 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

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

Strongly Correlated Two-Electron Transport in a Quantum Waveguide Having a Single Anderson Impurity [PDF]
, 2008 The strongly correlated two-electron transport in one-dimensional channel coupled with an Anderson-type impurity is solved exactly via a Bethe ansatz approach. We show that the transport properties are fundamentally different for spin singlet and triplet

Impurity ion transport by filamentary plasma structures
Nuclear Materials and Energy, 2019 We have studied the impurity ion transport by a filamentary plasma structure with the three-dimensional electrostatic particle-in-cell simulation. The effective diffusivity of the impurity ions transported by a filamentary plasma structure has been ...

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

Spin quadrupoletronics: moving spin anisotropy around [PDF]
, 2010 We show that spin anisotropy can be transferred to an isotropic system by transport of spin quadrupole moment. We derive the quadrupole moment current and continuity equation and study a high-spin valve structure consisting of two ferromagnets coupled to

Nuclear 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 ...

Effect of magnetic anisotropy on spin-dependent thermoelectric effects in nanoscopic systems [PDF]
, 2015 Conventional and spin-related thermoelectric effects in electronic transport through a nanoscopic system exhibiting magnetic anisotropy $-$with both uniaxial and transverse components$-$ are studied theoretically in the linear response regime.

Kondo effect and impurity band conduction in Co:TiO2 magnetic semiconductor [PDF]
, 2007 The nature of charge carriers and their interaction with local magnetic moments in an oxide magnetic semiconductor is established. For cobalt-doped anatase TiO2 films, we demonstrate conduction in a metallic donor-impurity band.

Stability of divertor detachment
Nuclear 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.
