Abstract: A novel six-port-cylindrical hohlraum has been independently designed for laser-driven inertial confinement fusion in China.Initial full-beam implosion experiment of this hohlraum was carried out on the laser facility.Integral experimental data with the convergence ratio from 10 to 20 were successfully obtained, and the best YOC_2D of the implosion was demonstrated up to 80.4%.
