Experimental study of X-ray emission properties of laser produced plasmas with Au and Au foam layer targets

The X-ray emission properties of Au plasmas consist of spectral distribution, M band fraction (2-4 keV), X-ray angular distribution and X-ray conversion efficiency, are imperative for various X-ray source applications. In order to investigate the X-ray emission properties of laser produced plasmas with Au and Au foam targets, experiments were carried out in Shenguang II laser facility. Au foam targets with densities of 0.6 and 0.4 g/cm3 were employed. The X-ray emission properties were measured. Excellent agreements of the experimental and theoretical spectral distributions and M band fractions were achieved.
