Abstract

Abstract

Laser-induced X-ray source is widely used in high energy density physics. The experiment studied the Pd L-band X-ray source produced from the 9th laser (400 J/1 ns/351 nm) irradiating 10 m Pd targets on Shenguang Ⅱ facility. The emission spectrum of Pd L-band X-ray was 2.9-3.6 keV. The conversion efficient of Pd L-band X-ray was 8%. The angular distributions measured in front of the targets could be fitted with the function of cos1/3. The experimental result shows that the Pd X-ray source has the advantage of proper X-ray wavelength and high brightness.
