Compared with central ignition of laser fusion, fast ignition separates compression and ignition thus it can relax the requirements for the implosion symmetry and the driven energy. Indirect drive pre-compression of cone-in-shell target for fast ignition was performed on Shenguang Ⅱ laser facility. The temporal evolution of the target was observed by the X-ray backlight framed camera. The density and areal density of the compressed fuel which were obtained from the backlight figures are 30 g/cm3 and 50 mg/cm2 separately. To minimize the mixing of the compressed fuel and cone high-Z vapor produced by the M-line emission from the gold holhraum, a CH foil was coated on the full outer surface of the cone. Experimental results and simulation results demonstrated that the coated CH foil could minimize the mixing effectively.
