Mass-Ablation-Rate Measurements in Polar-Direct-Drive Implosions on OMEGA

A new diagnostic technique has been developed on OMEGA to measure the mass ablation rate in direct-drive implosions. It is being applied to polar-direct-drive (PDD) experiments to validate the 2-D cross-beam energy transfer (CBET) and nonlocal thermal-conduction modeling.

Shown here is (a) an x-ray self-emission image measured on a symmetric-drive implosion on OMEGA, and (b) the simulated density (solid curve) and temperature used to calculate the x-ray emission profile (dotted black curve).
