Particle Dynamics in the RMP Ergodic Layer under the Influence of Edge Plasma Turbulence
Acta Polytechnica, 2013 The complex processes in edge tokamak plasma are affected (among others) both by resonant magnetic perturbation (RMP) and by plasma turbulence. RMP is nowadays considered to be a candidate for the mitigation of the edge-localized modes (ELMs). The effect

Impact of lower hybrid current drive on edge velocity shear and turbulence in the HL-2A tokamak
Nuclear FusionThe effect of lower hybrid current drive (LHCD) on edge velocity shear and turbulence in the HL-2A tokamak has been investigated. Experimental results demonstrate that the LHCD leads to an increase in edge velocity shear at both the inner and outer shear

Core plasma confinement during detachment transition with RMP application in LHD
Nuclear Materials and Energy, 2018 The core plasma confinement during detachment phase is investigated in the discharges with application of resonant magnetic perturbation (RMP) field in LHD. The RMP application creates a remnant magnetic island in the edge stochastic layer, which largely

High-Performance Edge-Contact Monolayer Molybdenum Disulfide Transistors
ResearchEdge contact is essential for achieving the ultimate device pitch scaling of stacked nanosheet transistors with monolayer 2-dimensional (2D) channels. However, due to large edge-contact resistance between 2D channels and contact metal, there is currently

Intermittent transport in edge plasmas
, 2004 The properties of low-frequency convective fluctuations and transport are investigated for the boundary region of magnetized plasmas. We employ a two-dimensional fluid model for the evolution of the global plasma quantities in a geometry and with parameters relevant to the scrape-off layer of confined toroidal plasmas.

Sensitivity analysis of plasma edge code parameters through algorithmic differentiation
Nuclear Materials and Energy, 2019 Anomalous radial transport coefficients, boundary conditions and reaction rates are among the main sources of uncertainty within plasma edge modeling. In principle, an analysis to determine the sensitivity of code results to changes in uncertain model ...

Effect of electron and ion mobility on edge biasing in tokamak plasmas
Nuclear FusionWe present an improved model for the study of edge biasing in a tokamak plasma that incorporates electron and ion mobility contributions. The non-ambipolar nature of the drifts due to the electron/ion mobility terms influences the space charge separation
