Implosion of Cone-in-shell Target on Shenguang Laser Facilities

Experiments of indirectly driven implosion of cone-in-shell target for fast ignition have been carried out on Shenguang II and Sheguang III prototype laser facilities. Empty CD shells are imploded using 8 beams on both laser facilities. The neutron yield was measured by the scintillator detectors. 106$\sim $107 neutrons were obtained in the experiments. On Shenguang II, the 9th beam was used to generate a Ti backlighter. The backlit image was measured via a X-ray framing camera with a time-gated resolution of 60 ps. On Shenguang III prototype, only self-emission of X-ray from the imploded shell was measured.
