Two shells with the diameter of 0.8–0.9 mm and a wall thickness of ≅1 μm were produced at the Lebedev Physics Institute for the experiments conducted at the ISKRA-5 facility. The results of two experiments with the aforementioned shells conducted at the ISKRA-5 facility with the use of an indirect-drive set up. In one of the experiments, the diameter of the golden hohlraum was D = 2 mm while in the other it was D = 4 mm. In these experiments it was observed to be ≅4 times the difference of the average laser intensity on the hohlraum surface. The results of computational analysis of the experiments are also presented here.

A novel approach for injection of a freestanding target into an ICF chamber is described which could significantly reduce both the dead volume of the target system and the fill time of cryotarget. The extremely short flight time of a target inside the ICF target chamber (less than 100 ms) allows one to keep the quality of the cryolayer up to the very moment of target irradiation. The possibility of improving the quality of the inner surface of the cryogenic layer by using the target illumination by the electron beams during the free fall of the target in the fusion chamber is also discussed.
