Nuclear Materials and Energy, 2019 The edge fluid code EDGE2D-EIRENE was used to compare the calculated low field side mid-plane separatrix temperature (Teu, sep) in the presence of seeding impurities with the two point model.

Separatrix parameters and core performances across the WEST L-mode database
Nuclear Fusion, 2023 WEST database analysis shows a correlation of the recycled neutral source around the separatrix with core performances. This observation questions the causality chain between particle source and turbulent transport up to the core in L-mode, high ...

Nuclear Fusion, 2023 In future fusion reactors disruptions must be avoided at all costs. Disruptions due to the density limit (DL) are typically described by the power-independent Greenwald scaling.

Approach to the separatrix with eccentric orbits [PDF]
SciPost Physics CoreEccentric binary compact mergers are prime targets of current and future gravitational wave observatories. In the small mass ratio expansion, post-adiabatic inspirals have been modeled up to the separatrix, where first-principle modeling currently ends ...

Physical Review Accelerators and Beams, 2019 Losses and component activation are limiting performance factors for slow extraction with high-power applications, and new techniques of loss-reduction, such as bent crystals, require a stable and narrow separatrix angular spread. Conventional tune-sweep

Current structure and flow pattern on the electron separatrix in reconnection region
Geoscience Letters, 2017 Results from 2.5D Particle-in-cell (PIC) simulations of symmetric reconnection with negligible guide field reveal that the accessible boundary of the electrons accelerated in the magnetic reconnection region is displayed by enhanced electron nongyrotropy

Electron Dispersion and Parallel Electron Beam Observed Near the Separatrix
Journal of Geophysical Research: Space Physics, 2019 The separatrix region is the region between the separatrix and the reconnection jet. Due to the E×B drift and velocity filter effect in which high‐energy particles with high parallel speed can be seen prior to low‐energy particles along the field line ...

FastQSL: A Fast Computation Method for Quasi-separatrix Layers [PDF]
Astrophysical Journal, 2022 Magnetic reconnection preferentially takes place at the intersection of two separatrices or two quasi-separatrix layers, which can be quantified by the squashing factor Q, whose calculation is computationally expensive due to the need to trace as many ...

The separatrix operational space of ASDEX Upgrade due to interchange-drift-Alfvén turbulence
Nuclear Fusion, 2021 The efficient operation of a tokamak is limited by several constraints, such as the transition to high confinement or the density limits occurring in both confinement regimes. These particular boundaries of operation are derived in terms of a combination
