Abstract

We have studied the shock induced pressures due to the interaction of soft X-ray thermal radiation with foam-layered metal targets. Thermal X-ray radiation was produced by focusing a high energy laser inside a small size hohlraum. Experiments were performed using a 3ω converted (λ=0.44 μm) Iodine laser of τ≈450 ps (FWHM) duration. An increase in shock pressure was observed with the foam layered targets as compared to bare metal targets. Results are analyzed on the basis of the role of foam density and thickness.
