Reduced physics model of the tokamak Scrape-Off-Layer for pulse design
Nuclear Materials and Energy, 2023 The dynamic interplay between the core and the edge plasma has important consequences in the confinement and heating of fusion plasma. The transport of the Scrape-Off-Layer (SOL) plasma imposes boundary conditions on the core plasma, and neutral ...

Scaling laws for electron kinetic effects in tokamak scrape-off layer plasmas
Nuclear Fusion, 2023 Tokamak edge (scrape-off layer (SOL)) plasmas can exhibit non-local transport in the direction parallel to the magnetic field due to steep temperature gradients.

On the Turbulent Behavior of a Magnetically Confined Plasma near the X-Point
Fluids, 2022 We construct a model for the turbulence near the X-point of a Tokamak device and, under suitable assumptions, we arrive to a closed equation for the electric field potential fluctuations.

Divertor erosion at ASDEX Upgrade during helium plasma operations
Nuclear Materials and EnergyThe effect of helium plasma operation on the erosion of plasma-facing components at the low-field side divertor of ASDEX Upgrade was investigated during the 2022 helium experimental campaign. A set of tungsten-covered graphite samples with small platinum

Detachment scalings derived from 1D scrape-off-layer simulations
Nuclear Materials and EnergyFusion power plants will require detachment to mitigate sputtering and keep divertor heat fluxes at tolerable levels. Controlling detachment on these devices may require the use of real-time scrape-off-layer modeling to complement the limited set of ...

Kinetic simulations of electron heat flux in the scrape-off layer
Nuclear Materials and Energy, 2017 Parallel electron heat flux qe|| on open field lines is studied with the 1D2V kinetic Vlasov-Fokker-Planck (VFP) code KIPP [15–17]. In order to assess the importance of kinetic effects on the scrape-off layer heat transport in a systematic way, a series ...

Effect of local wall clearance on scrape-off layer electron density profiles in ASDEX Upgrade
Nuclear FusionThe plasma electron density is measured with multiple diagnostics in the scrape-off layer of the ASDEX Upgrade tokamak. The recorded values are typically in good agreement in the case of exponentially decaying profiles at low densities, but they become ...

Blob stability and transport in the scrape-off-layer [PDF]
Physics of Plasmas, 2003 High-density plasma filaments extended along the magnetic field, which look like “blobs” in the plane perpendicular to B, have been observed in the scrape-off-layer (SOL) of many plasma devices. These objects become polarized and subsequently E×B drift to the wall carrying a significant flux of particles.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Molecular Oncology, EarlyView.Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.
