Abstract. To test high gain targets surrogated in the planar geometry, we
have constructed a new experimental system (HIPER) which provides the high
ablation pressure with a uniform irradiance profile. These performances were
achieved by bundling twelve beams of the existing GEKKO XII into a F/3 focus
cone. The partially coherent light is introduced for the beam smoothing of a
green foot pulse consisting of three beams, and the three-directional
smoothing by spectral dispersion is utilized for residual nine beams
delivering a blue main drive pulse. The detail of design concept and results
of initial activation of this system are reported.
