?Influencing factors in forming uniform plastic shells for laser fusion targets

In laser fusion experiments, fuel capsules with high sphericity and high wall-thickness uniformity are often fabricated by density matched emulsion method. The paper investigates the influences of the interfacial tension, viscosity of oil phase, size and thickness of shell in the fabrication process by T.Norimatsus model. The results indicate that bigger interfacial tension and smaller size of shell lead to better uniformity. The viscosity of oil phase may have different effects on uniformity, when the outer oil surface moves in different forms.
