Super Guassian Distribution of Laser Produced Plasmas
Kaifeng Chen
TL;DR
This paper investigates the distribution of laser-produced plasmas, focusing on the competition between inverse Bremsstrahlung and thermalization, supported by formulas and Fokker-Planck simulations.
Contribution
It introduces a model describing the super-Gaussian distribution in plasmas considering inverse Bremsstrahlung and self-collisions, with numerical validation.
Findings
Distribution tends towards super-Gaussian due to inverse Bremsstrahlung
Thermalization through self-collisions counteracts this effect
Numerical results support the theoretical formulas
Abstract
The competition between inverse Bremsstrahlung, which pushes the distribution towards a super-Guassian, and the thermalization through self-collisions is considered. In the summary, basic formulas are provided and some numerical results by Fokker-Planck simulation are plotted.
