ABSTRACT:
Targets for high energy beams, such as laser beams, produced in laser fusion apparatus are described. The targets are porous spheres of deuterated hydrocarbon material, particularly deuterated polyethylene. The spheres are small and have diameters in the range of 50 to 300 microns. Higher neutron yields are obtained from these targets than from solid targets of similar materials, (viz., spherical targets of much higher density). Methods of fabricating the targets by forming them into solid spheres, cross linking their molecules and causing them to swell such that the resultant targets have a microscopically small sponge-like structure, are also described.
