Initial indirect cone-in-shell fast ignition integrated experiment was carried out on Shenguang Ⅱ-updated laser facility. The shaped laser pulses were injected into a hohlraum to compress a cone-in-shell target and achieve a higher density. Then a picosecond laser with hundreds joules energy was guided by a golden cone to irradiate the tip of the cone and generate hot electron flux to heat the compressed deuterium fuel. A maximum neutron yield of 2.2105 was observed at a suitable injection timing of the picosecond laser, which is 44 times larger than that with no picosecond laser injection. These experiment results confirm the heating effect of the picosecond igniting laser.
