Thermal transport in warm dense matter revealed by refraction-enhanced x-ray radiography with a deep-neural-network analysis

Communications Physics, 2023
Transport properties of high energy density matter affect the evolution of many systems, ranging from the geodynamo in the Earth’s core, to hydrodynamic instability growth in inertial confinement fusion capsules.

Self-similar structure and experimental signatures of suprathermal ion distribution in inertial confinement fusion implosions [PDF]

, 2015
The distribution function of suprathermal ions is found to be self-similar under conditions relevant to inertial confinement fusion hot-spots. By utilizing this feature, interference between the hydro-instabilities and kinetic effects is for the first ...

Neutron time-of-flight measurements of charged-particle energy loss in inertial confinement fusion plasmas [PDF]

, 2019
Neutron spectra from secondary ^{3}H(d,n)α reactions produced by an implosion of a deuterium-gas capsule at the National Ignition Facility have been measured with order-of-magnitude improvements in statistics and resolution over past experiments.

Generation of a sharp density increase in radiation transport between high-Z and low-Z plasmas

Matter and Radiation at Extremes, 2016
A sharp density increase (referred to as density incrustation) of the Au plasmas in the radiative cooling process of high-Z Au plasmas confined by low-Z CH plasmas is found through the radiative hydrodynamic simulations.
