Abstract

A frequency-doubled laser beam of the Nd:glass kilojoule nanosecond LULI2000 facility (1.5 ns duration, 200–400 J energy, 0.53 μm wavelength) was focused on a Xe or Kr gas jet. The plasma was simultaneously diagnosed with X-ray (in the wavelength range of 6–8 A for Kr and of 12–15 A for Xe) and time-resolved XUV (20–200 A) emission spectroscopy. Electron density and temperature as well as the ionization charge were measured by time-resolved Thomson scattering of the heating laser pulse. The spectra are compared with the calculations performed with the NLTE collisional-radiative code AVERROES/TRANSPEC. Best fits of the X-ray and XUV spectra obtained are presented. The measured charge distribution and dynamics is analyzed using the simultaneous Thomson scattering diagnostic.
