Abstract

Spectrum and energy measurements of X-ray radiation emitted by partially transparent Fe and Al plasmas have been carried out for thin-layered inverted-corona targets on the ISKRA-5 laser facility. The targets were plastic spherical (2-mm diam) shells of 4.6 mm thickness having 0.25 mm Fe or 0.65 mm Al thin inner coatings. The energy radiated in Heα and Lyα resonance lines of Fe and Al ions was measured as well. Experimental data and results of numerical calculations are compared. Measured laser light to X-ray conversion coefficient has been found to be essentially low, then calculated one for both Fe and Al coated targets. Possible reasons for this discrepancy are discussed.
