“…This method allows determining the projectile ion charge and velocity as a function of the ion penetration depth in the stopping medium. The high spectral (l/Dl ¼ 2000-5000) and spatial (30 -70 mm) resolutions were achieved using a spherically bend crystal spectrometer and Kodak X-ray films (Faenov et al, 1994;Rosmej et al, 2002).…”

“…During the penetration in a stopping medium, the ion velocity and therefore the Doppler shift are decreasing continuously imaging the deceleration process. A high spectral resolution (l/dl ¼ 3000) of the spherically bend mica spectrometer (Faenov et al, 1994) allows obtaining the ion velocity dependence with the penetration depth using the Doppler line shift with Fig. 1.…”

The dependence of calcium ion subshell populations on the target density during the ion stopping process was analyzed using a five charge-state collisional-radiative model. The model, which consists of the ground and three excited states for every ion charge, was successfully compared with the experiment. The gas-solid difference of calcium ion charge state distribution has been numerically demonstrated. For Ca projectiles with energies of 4-11 MeV/u, the increase of the mean ion charge in solid target is explained by the increase of the total ionization rate and by suppression of the bound electron capture process at high densities of the stopping medium.

“…Meanwhile, the holes in the mirror and focusing lens affect the laser radiation flux density at the center of the focusing area decreasing the intensity to the value about 2 × 10 11 W/cm 2 . The soft X-ray line radiation from the plasma in the direction normal to the target surface was studied with the spherically bent mica crystal spectrograph (Faenov et al, 1994;Skobelev et al, 1995). The curvature radius of a crystal was 150 mm.…”

The two-temperature, 2D hydrodynamic code Hydro-ELectro-IOnization-2-Dimensional (HELIO2D), which takes into account self-consistently the laser energy absorption in a target, ionization, heating, and expansion of the created plasma is elaborated. The wide-range two-temperature equation of state is developed and used to model the metal target dynamics from room temperature to the conditions of weakly coupled plasma. The simulation results are compared and demonstrated a good agreement with experimental data on the Mg target being heated by laser pulses of the nanosecond high-energy laser for heavy ion experiments (NHELIX) at Gesellschaft fur Schwerionenforschung. The importance of using realistic models of matter properties is demonstrated.

Soft x-ray emission from a Mather-type plasma-focus device (PF-1000) operated at ∼400 kJ was measured. The high density and temperature plasma were generated by the discharge in the deuterium-argon gas mixture in the modified (high-current) plasma-focus configuration. A spherically bent mica crystal spectrograph viewing the axial output of the pinch region was used to measure the x-ray spectra. Spatially resolved spectra including the characteristic x-ray lines of highly ionized Ar and continua were recorded by means of an x-ray film. The x-ray emission of PF-1000 device was studied at different areas of the pinch.
