Abstract

Abstract

Fast ignition of laser inertial confinement fusion separates the compression and ignition, thus relaxes the requirements on compression symmetry and energy. In the experiments of pre-compression of cone-in-shell target for fast ignition on Shenguang Ⅱ laser facility, the framed X-ray backlight images show that the existence of cone and guiding wire does not affect the implosion process, which has been demonstrated by the agreement of experimental results and one-dimensional radiation hydrodynamic simulation results. Adjusting the position of cone and fuel capsule, the cone can be kept robust until the stagnation, which is crucial for the transport and deposit of hot electrons.
