X-ray Thomson scattering technique for diagnosing dense plasma was demonstrated on Shenguang-Π laser facility.Laser plasma x-ray source of titanium He-α lines (～4.75keV),generated by laser beam (1.5kJ/527nm/2ns) heated titanium thin foil,was used as x-ray probe beam.The x-ray probe was then scattered by cold CH foam column of 1g/cm3 density.The scattered radiation at 90 was diffracted by polyethylene terephthalate (PET) crystal and recorded on x-ray charge-coupled device.Well-defined scattering spectra were obtained with good signal to noise ratio.

Laser plasma x-ray source of titanium He-α lines (~ 4.75 keV), generated by laser beam (1.5 kJ / 527 nm / 2 ns) heated titanium thin foil, was used as an x-ray probe beam then scattered by cold CH foam column of 1 g / cm3 density. The scattered radiation at 90 was diffracted by polyethylene terephthalate (PET) crystal and recorded on x -ray charge-coupled device were well-defined scattering spectra were obtained with good signal to noise ratio.
