Estimate of pre-thermal quench non-thermal electron density profile during Ar pellet shutdowns of low-density target plasmas in DIII-D [PDF]

, 2021
The radial density profile of pre-thermal quench (pre-TQ) early-time non-thermal (hot) electrons is estimated by combining electron cyclotron emission and soft x-ray data during the rapid shutdown of low-density (ne≲1019m−3) DIII-D target plasmas with ...

Lifetime of Quasiparticles in Hot QED Plasmas [PDF]

Physical Review Letters, 1996
The calculation of the lifetime of quasiparticles in a QED plasma at high temperature remains plagued with infrared divergences, even after one has taken into account the screening corrections. The physical processes responsible for these divergences are the collisions involving the exchange of very soft, unscreened, magnetic photons, whose ...

Cassini encounters with hot flow anomaly-like phenomena at Saturn's bow shock [PDF]

, 2008
The first observations of the kronian equivalent of hot flow anomalies (HFAs) are presented. Using magnetic field and plasma data we discuss two events that were observed upstream of Saturn's bow shock during the first two orbits of the Cassini ...

Ionization potential depression in dense iron plasmas near solid density

Results in Physics, 2022
In a dense hot plasma, the energy levels of an embedded ion are lowered by the induced screening potential, which is termed as the ionization potential depressions (IPDs) for the continuum levels.

Contribution of Lienard-Wiechert Potential to the Electron Broadening of Spectral Lines in Plasmas

Atoms, 2018
Lienard-Wiechert or retarded electric and magnetic fields are produced by moving electric charges with respect to a rest frame. In hot plasmas, such fields may be created by high velocity free electrons.

Extended application of Kohn-Sham first-principles molecular dynamics method with plane wave approximation at high energy-From cold materials to hot dense plasmas [PDF]

, 2016
An extended first-principles molecular dynamics (FPMD) method based on Kohn-Sham scheme is proposed to elevate the temperature limit of the FPMD method in the calculation of dense plasmas.

Self-organization of hot plasmas the canonical profile transport model [PDF]

, 2015
In this monograph the author presents the Canonical Profile Transport Model or CPTM as a rather general mathematical framework to simulate plasma discharges.The description of hot plasmas in a magnetic fusion device is a very challenging task and many ...

Adaptive Algorithm for the Generation of Superconfigurations in Hot-Plasma Opacity Calculations

Plasma, 2022
In hot plasmas, such as the ones encountered in astrophysics or laser-fusion studies, the number of ionic excited states may become huge, and the relevant electron configurations cannot always be handled individually.

Science with hot astrophysical plasmas [PDF]

, 2017
We present some recent highlights and prospects for the study of hot astrophysical plasmas. Hot plasmas can be studied primarily through their X-ray emission and absorption.

Spaced resolved analysis of suprathermal electrons in dense plasma

EPJ Web of Conferences, 2013
The investigation of the hot electron fraction is a crucial topic for high energy density laser driven plasmas: first, energy losses and radiative properties depend strongly on the hot electron fraction and, second, in ICF hohlraums suprathermal ...
