Abstract
One of the key problems in the ICF program is the development of rapid methods for forming cryogenic fuel targets (CFT) for their feeding to the focus of a high-power laser setup or an ICF reactor. The simulation results on temporal parameters of the formation of reactor-scaled CFTs by the free-standing target (FST) method are presented. The CFT design includes hollow 4-mm-diameter shells of compact and porous polymers, containing solid hydrogen fuel on the inner surface. It is shown that the time of the cryogenic layer formation in the targets does not exceed 30 s, which makes it possible to implement line production of reactor-scaled CFTs based on the FST method.
