Hohlraum targets are a special class of ICF targets, in which capsule ablation is driven by the thermal radiation inside a cavity, the so-called hohlraum. In this scheme, the laser or ion beams do not drive the capsule directly, and one therefore calls it indirect drive. Expressions for X-ray conversion efficiency are derived for incident laser and ion beams. Radiation confinement inside the cavity is discussed in terms of the wall albedo, which measures the re-emission of absorbed radiation by the heated wall. The radiative transfer between the walls is treated approximately by means of the viewfactor method. Simple estimates are derived for the hohlraum temperature of the black-body radiation. Simulations of radiatively driven implosions are presented in the context of targets for ion beam fusion.

Keywords:   indirect drive, X-ray conversion efficiency, radiation confinement, wall albedo, black body radiation, hohlraum temperature, radiatively driven implosion, viewfactor, ion beam fusion
