Electron Temperature Measurements of Model Ne-Like X-Ray Laser Plasmas From Resonance keV Spectra

摘要

We present results of temperature measurements of Ne-like Zn plasmas created by an intense laser pulse, using slab targets. Pulses with typical energy of 50 J in 300 ps were focused to a line or point foci, in which the pumping pulse energy was varied from shot to shot,. The electron temperature in dependence on the pulse energy and irradiation intensity is studied. The temperature is inferred spectroscopicalry from a set of selected Ne-like spectral lines. The experimental results are compared with the numerical simulations made by the hydrodynamic code EHYBRID.
