摘　　要：The octahedral spherical hohlraum provides an ideal and practical approach for indirect-drive toward a dream fusion with predictable andreproducible gain and opens a route to the development of a laser drive system for multiple laser fusion schemes. This paper addressesa number of issues that have arisen with regard to octahedral spherical hohlraums, such as how to naturally generate a highly symmetricradiation drive at all times and for all spectra without the use of symmetry tuning technology, how to determine the three-dimensional,temporal, and spectral characteristics of the real radiation drive on a capsule in experiments, and the relative energy efficiency of an octahedralspherical hohlraum compared with a cylindrical hohlraum. A design island for an octahedral spherical hohlraum is presented. Finally, thechallenges and future tasks for the path forward are presented.
