Radiation symmetrization within spherical, ellipsoidal and cylindrical hohlraum targets for heavy-ion intertial-confinement fusion (ICF) is studied by means of a 3D numerical static model, in which realistic assumptions are made concerning the geometry of the system and, particularly, of the radiation «converters». Among the systems so far studied, only spherical hohlraums with six converters achieve the illumination symmetry of the fusion capsule considered necessary for ICF applications. A parametric study of cylindrical hohlraums enlightens the effect of several parameter changes, and suggests directions for further studies, aiming at the design of two-converter targets. © 1993 Società Italiana di Fisica.
