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.
