In this paper we present time-resolved temperature measurements of a radiatively heated, thin tamped foil via Kα absorption spectroscopy. The sample foil was 1500 A MgO, tamped on both sides with 1000 A paralyene, and was heated by soft x-rays trans

The design and analysis of plasma spectroscopy experiments can be significantly complicated by relatively routine computational tasks arising from the massive amount of data encountered in the experimental design and analysis stages of the work. Diff

The growth due to the Rayleigh–Taylor (RT) instability of single‐wavelength surface perturbations on planar foils of brominated CH [CH(Br)] and fluorosilicone (FS) was measured. The foils were accelerated by x‐ray ablation with temporally shape
