We have constructed the HIPER laser system that combines all 12 beams of the existing GEKKO XII laser to irradiate a target from one side.The laser pulse in standard operation consists of partially coherent light for foot (green) and two-dimensional SSD for main drive (blue). We will test in the first series of experiment the ablation pressure and its uniformity, ablative Rayleigh-Taylor instability, and instability at explosion phase.　 Although the primary objective is to test hydrodynamic stability of an ignition target (both in fast ignition and conventional self-ignition), the HIPER laser is expected to be a major tool for a number of high energy-density physics, such as laboratory astrophysics, equation-of-state study.
