A confinement chamber for Inertial Confinement Fusion (ICF) may include a closed hohlraum and ICF target wherein the ICF target may comprise a central spherical fuel region, inner shell, outer fuel region, outer shell, and propellant region. A multitude of cylindrical beam channels may penetrate the entire thickness of the hohlraum. At the end of each cylindrical beam channel, where they exit the hohlraum, is a hemispherical cavity. Centered in the curvature of each cavity, and coaxial with each beam channel is a gold foam radiator. By layering materials or grading the density of a material in the propellant region of the closed hohlraum ICF target, the pressure profile on the outer shell may be tailored.
