Journal ArticleDOI
Thermal equilibrium and prehydration processes of electrons injected into liquid water calculated by dynamic Monte Carlo method
TL;DR: In this article, the thermalization length and spatial distribution of electrons in liquid water were simulated for initial electron energies ranging from 0.1 eV to 100 eV using a dynamic Monte Carlo code.
Journal ArticleDOI
Analysis of x-ray polarization to determine the three-dimensionally anisotropic velocity distributions of hot electrons in plasma produced by ultrahigh intensity lasers.
TL;DR: Results demonstrate that the polarization degrees are sensitively dependent on the profile of the electron velocity distributions which are affected by the polarization of the laser pulse.
Journal ArticleDOI

TL;DR: In this paper, an experimental study on energy transport in ultra-high intensity laser plasma was made, where X-ray emission from a triple-layer target irradiated at 10 19 W cm -2 was observed with x-ray spectrographs, monochromatic imagers and an xray polarimeter to provide a temperature profile in the depth of the target.
