Thomson Scattering from High-ZLaser-Produced Plasmas

Abstract

We present the first simultaneous observations of ion acoustic and electron plasma waves in laserproduced dense plasmas with Thomson scattering. In addition to measuring the standard plasma parameters, electron temperature and density, this novel experimental technique is shown to be a sensitive method for temporally and spatially resolved measurements of the averaged ionization stage of the plasma. Experiments with highly ionized gold plasmas clearly show that the inclusion of dielectronic recombination in radiation-hydrodynamic modeling is critically important to model cooling plasmas.[S0031-9007(98)

Thomson scattering from laser plasmas

“…Equation (9) indicates that the electron P density of the plasma can be obtained with high accuracy. For this purpose, the electron temperature must be self-consistently obtained from the epw spectrum which is possible as the electron plasma wave is heavily damped by electron Landau damping.…”

Observation of High Soft X-Ray Drive in Large-Scale Hohlraums at the National Ignition Facility

“…In those experiments, the DCA model was a better fit to the measurements [21,22]. Those experimental measurements also show the deficiency with the flux limited diffusion model.…”

Collective Thomson scattering from high-temperature high-density plasmas revisited

“…We can see that the correction in the first order of v/c is negligible. However, scattering spectra from thermal electron plasma waves are also successfully measured in laser-produced plasmas [4].…”
