Abstract
We report the development of a new comparison method used to estimate the electron temperature T
e of heavy-element plasmas and high-temperature iron laser-produced plasmas. To this end, two laser-produced plasmas – magnesium plasmas and iron plasmas – were studied at identical laser radiation fluxes on the target. Plasma diagnostics was performed using X-ray spectra of H- and He-like Mg ions. VUV spectra of Fe ions were recorded in the wavelength range 15 – 150 Å As a result, the change in the structure of the VUV spectra of Fe ions as a function of T
e in the range of 100 – 400 eV was studied. These data are necessary for diagnosing plasma sources containing the iron element.
