A time-resolved X-ray conversion efficiency campaign
was conducted at CEA/Limeil–Valenton on the PHEBUS
laser, with Au planar targets. The calibrated diagnostic
DEMIXART has measured X-ray emissions driven by shaped
laser pulses. The results have been analyzed with the
“physicist” 1D1/2 hydrodynamical code CHIVAS,
where improved transport coefficients have been implemented.
The influence of the degeneracy and solid/liquid corrections
on various parameters is shown. Other significant effects
due to focal spot shapes and lateral conduction are quantified
with the FCI2 hydroradiative code of CEA/DRIF.
