Research of areal density diagnostic technique on Shenguang III laser prototype facility

In the test run of Shenguang III laser prototype facility, under the low density condition, the yield ratio method was used to measure the fuel areal density. Considering the uncertainty of the neutron yield, detectors with different efficiencies were used. The clear secondary-neutron signals in ine...

Description
Summary:In the test run of Shenguang III laser prototype facility, under the low density condition, the yield ratio method was used to measure the fuel areal density. Considering the uncertainty of the neutron yield, detectors with different efficiencies were used. The clear secondary-neutron signals in inertial confinement fusion experiments were obtained for the first time in China, and the values of the areal density were deduced.
