Abstract:
The effect of induced transparency of thin Al foils radiatively heated by intense extreme ultraviolet (EVU) radiation has been observed. The radiation of the plasma of Z-pinches appearing under the compression of tungsten liners at the Angara-5-1 facility has been used as the radiation that heats the Al foil (peak illumination on the foil $\sim$0.55 TW/cm$^2$) and is transmitted through it. The photoabsorption has been studied in the formed aluminum plasma at temperatures of 10-30 eV in the density range of $\sim$1–20 mg/cm$^3$ in the wavelength range of $\sim$5–24 nm. Absorption lines of Al$^{4+\dots7+}$ ions have been identified in the experimental spectrum. In addition, radiative gas-dynamic simulations of the foil heating and expansion have been performed taking into account radiation transfer processes.
