Özet

Simulation of the Ne-like Fe plasma is performed by using hydrodynamic and atomic physics code EHYBRID. The atomic physics data are obtained by using the Cowan code. In the simulation, a slab target is assumed to be irradiated by Nd:glass laser with double pulse configuration for producing Ne-like Fe plasma. In this study, effects of prepulse duration, prepulse intensity and time interval between prepulse and main pulse on absorption of main pulse energy are investigated. The general plasma properties such as absorbed energy, electron temperature, electron density, plasma expansion velocity distributions are calculated for prepulse duration varying from 0,50 ns to 2,00 ns.
