Experimental study of the plasma conditions in gas-filled hohlraum

ORAL

Abstract

Hohlraum plasma and its kinetic behavior are vital to study the laser heated hohlraum, affecting the temporal, spatial and spectral features of the x-ray source. Accurate measurements of the plasma conditions in gas-filled hohlraum have been achieved using the recently set-up 4$\omega $ Thomson scattering diagnostic at Shenguang-III prototype laser facility. The plasma evolution and kinetic behavior for different locations inside the hohlraum are explored through compareing the theoretical Thomson-scattering spectra based on radiation hydrodynamic code to the experiment result.
