Experimental studies on X-ray radiation from Hohlraum targets illuminated with two beams

Experiments to study radiation properities of Hohlraum targets with two laser beams illumination from both sides are described. Two sub-keV X-ray spectrometers with time correlation were used to measure X-ray spectra of the conversion region and the implosion region, respectively. The X-ray spectra, radiation temperature, X-ray time spectrum and the relation of temperature with time were obtained. At the same time, many shots with different types of Hohlraum were taken to study the relation of radiation temperature in the conversion region with input laser power density. One of the spectrometer channels was installed with a grazing incidence reflection mirror which gave nice results
