Plasma edge and plasma-wall interaction modelling: Lessons learned from metallic devices

Nuclear Materials and Energy, 2017
Robust power exhaust schemes employing impurity seeding are needed for target operational scenarios in present day tokamak devices with metallic plasma-facing components (PFCs). For an electricity-producing fusion power plant at power density Psep/R>15MW/

Experimental characterization of the quasi-coherent mode in EDA H-Mode and QCE scenarios at ASDEX Upgrade

Nuclear Fusion, 2023
The quasi-coherent mode (QCM), appearing in enhanced D $_{\alpha}$ high confinement mode (EDA H-mode) and quasi-continuous exhaust (QCE) plasmas has been analysed in detail at ASDEX Upgrade via thermal helium beam spectroscopy under various discharge ...

Factor Design for the Oxide Etching Process to Reduce Edge Particle Contamination in Capacitively Coupled Plasma Etching Equipment

Applied Sciences, 2022
During the oxide layer etching process, particles in capacitively coupled plasma etching equipment adhere to the wafer edge and cause defects that reduce the yield from semiconductor wafers.

Quantum Hall edges beyond the plasma analogy

Physical Review Research
We demonstrate that the widely used plasma analogy is unreliable at predicting edge properties of quantum Hall states. This discrepancy arises from a fundamental difference between quantum Hall droplets and plasmas (Coulomb gases): The former are ...

Aerodynamic drag reduction for a truck model using DBD plasma actuators

Advances in Mechanical Engineering, 2022
In this study, the effect of DBD plasma actuator based active flow control for a truck model was investigated. Two different electrode shapes which are linear and comb-shaped plasma actuators, are considered.

Time-resonant tokamak plasma edge instabilities? [PDF]

Plasma Physics and Controlled Fusion, 2014
For a two week period during the Joint European Torus (JET) 2012 experimental campaign, the same high confinement plasma was repeated 151 times. The dataset was analysed to produce a probability density function (pdf) for the waiting times between edge-localised plasma instabilities ("ELMS"). The result was entirely unexpected.
