EXPERIMENTAL INVESTIGATION OF X-RAY RADIATION CHARACTERIZATION FOR CAVITY TARGETS

The experimental investigation of X-ray radiation characterized by the cavity targets was carried out at the Shenguang laser facility. The temperature profile along the axis of the cavity target was given. The first X-ray radiation from the laser heating phase and the second X-ray radiation from the expanded plasma collision phase were measured. The time interval between the two radiations was about 1.2 ns. The spectrum of the radiation from the implosion region was similar to a Planck spectrum.
