Efficient numerical simulation of atmospheric pulsed discharges by introducing deep learning

open access: yesFrontiers in Physics, 2023
Plasma simulation is an important but sometimes time-consuming approach to study the discharge behaviors of atmospheric pulsed discharges. In this work, an efficient simulation method is proposed by introducing deep learning to investigate the discharge ...

Mid-point electron density profiles from oblique ionograms

open access: yesAnnals of Geophysics, 1996
A computationally efficient technique for the inversion of oblique ionograms into mid-point electron density profiles is described. The profile is given as the sum of quasi-parabolic functions suitable for ray tracing.

Tracing electron density changes in langbeinite under pressure

open access: yesIUCrJ, 2022
Pressure is well known to dramatically alter physical properties and chemical behaviour of materials, much of which is due to the changes in chemical bonding that accompany compression.

One-Electron State of a Partially Ionized High-Z Ion [PDF]

open access: yes, 1988
An effective potential of an isolated partially ionized high-Z ion, calculated within the framework of the statistical models of atoms, is injected into the one-electron Schrödinger equation, in view of evaluating the electron density and comparing it ...

THE EFFECTS OF SOLAR ACTIVITY: ELECTRONS IN THE TERRESTRIAL LOWER IONOSPHERE [PDF]

open access: yesZbornik Radova: Geografski institut "Jovan Cvijić", 2017
Solar flare X-ray energy can cause strong enhancements of the electron density in the Earth’s atmosphere. This intense solar radiation and activity can cause sudden ionospheric disturbances (SIDs) and further create ground telecommunication interferences,

Large density amplification measured on jets ejected from a magnetized plasma gun [PDF]

open access: yes, 2007
Observation of a large density amplification in the collimating plasma jet ejected from a coplanar coaxial plasma gun is reported. The jet velocity is ~30 km s^-1 and the electron density increases from ~10^20 to 10^(22–23) m^-3.

Intermittent electron density and temperature fluctuations and associated fluxes in the Alcator C-Mod scrape-off layer [PDF]

open access: yes, 2018
The Alcator C-Mod mirror Langmuir probe system has been used to sample data time series of fluctuating plasma parameters in the outboard mid-plane far scrape-off layer. We present a statistical analysis of one second long time series of electron density,

An effective potential of electron-electron interaction in semi-infinite jellium

open access: yesCondensed Matter Physics, 2006
An effective potential of electron-electron interaction and a two-particle "density-density" correlator are calculated for semi-infinite jellium. Their asymptotics at large distances between electrons are studied in a plane parallel to the surface.

Understanding the core density profile in TCV H-mode plasmas

open access: yes, 2012
Results from a database analysis of H-mode electron density profiles on the Tokamak \`a Configuration Variable (TCV) in stationary conditions show that the logarithmic electron density gradient increases with collisionality.
