Paper Abstract

In this paper line x-ray emission from aluminum plasma at wavelength within range of 5 - 7 angstrom was studied numerically. The plasma was assumed to be produced by irradiating of aluminum target by long laser pulses (1000 psτp50 ps) at intensities up to I = 5×1016Wcm-2. The plasma hydrodynamics was simulated by EHYBRID code. Using the data from this code and Saha-Boltzmann equation; the x-ray spectrum and total x-ray yield of the plasma were calculated within the time scale of irradiation. The influences of laser intensity as well as pulse duration on the total yield of x-ray line emission were investigated. The results show that, the emitted x-ray lines at the above wavelength range has duration similar to that of the laser pulse and the total x-ray yield can be increased by increasing laser intensity and pulse duration.
