X-ray emission from plasmas produced by focusing the beam of a Nd laser on massive Al or Cu targets was studied. The temporal evolution of the emission was investigated by using an X-ray streak-camera. The spectral analysis of the emission was performed with both low and high resolution. The X-ray conversion efficiency, in the investigated spectral region, was measured to be 1% for Cu and slightly lower for Al. Two main spectral components were observed in the emission. In the case of Cu target, the first component was found to be centred at approximate to 1.2 keV and the second, whose intensity was measured to be 10(-3) of the previous component, at approximate to 7 keV. From line intensity ratios, obtained from high resolution spectra, we could estimate temperature and density of the emitting region.

Abstract

X-ray emission from plasmas produced by focusing the beam of a Nd laser on massive Al or Cu targets was studied. The temporal evolution of the emission was investigated by using an X-ray streak-camera. The spectral analysis of the emission was performed with both low and high resolution. The X-ray conversion efficiency, in the investigated spectral region, was measured to be 1% for Cu and slightly lower for Al. Two main spectral components were observed in the emission. In the case of Cu target, the first component was found to be centred at approximate to 1.2 keV and the second, whose intensity was measured to be 10(-3) of the previous component, at approximate to 7 keV. From line intensity ratios, obtained from high resolution spectra, we could estimate temperature and density of the emitting region.
