| 摘 要： | Eight beams 0.35μm laser with pulse duration of about 1.0ns and energy of 260J per beam was injected into a cylindrical cavity to generate intense x-ray radiation on the “Shengguang Ⅱ“ high power laser facility.Gold foils with a thickness in the range of 0.09-0.52μm were attached on the diagnostic hole of the cavity and ablated by the intense x-ray radiation.The propagating radiation heat wave in the high-Z gold plasma was observed clearly.For comparison,we also simulated the experimental results.
