Radiochemistry and secondary reactions for the diagnostics of laser-driven fusion plasmas

Abstract
Radiochemical measurements have been developed for the diagnostics of laser‐driven implosion plasmas. The excellent calibration for neutron‐yield measurement has been done using β‐γ coincidence technique. The multiactivable tracer method has been examined for measuring the pusher areal density by means of a high‐purity germanium detector. The first experimental success of the secondary nuclear fusion reaction method is also demonstrated for the direct measurement of the fuel ρR.
