Abstract
A high Z cylindrical hohlraum was used to produce xray radiation flux, whic h was used to drive shock waves in an Al step sample. The radiation temperature i s 15 5eV. Experiments were carried ont on `Shenguang II' laser facility, with eight 2 50J, 0.35μm wavelength, 1ns Gaussian laser pulses. The planar and preheatfre e s ho ck wave was generated and a clear image of shock and preheat wave was obtained . The shock wave velocity and pressure was 31.2km/s and 17.5×1011Pa, respectively.The radiation temperature measured by streaked pyrometer, was consistent with th at measured with a soft x-ray spectrometer which views through the laser entran ce hole.
