Analysis of the conditions of experiments on the compression of capsules with a foam absorber at Iskra V facility

The compression conditions are analyzed and the capsules are discussed for the energy of ∼2 kJ and pulse duration of ∼0.5 ns at the second harmonic of an iodine laser (λ 0.66 μm) under irradiation by a small number of beams at Iskra V facility (the facility has 12 beams, which are focused in a certain way onto the capsule). The authors consider different capsules filled with DT gas: the glass capsules (the inner radius is 260 μm; the thickness, 1.2-1.3 μm; the aspect ratio A 200) experimentally examined with Iskra V; the capsules made of polystyrene (R 140-170 μm; δ 5-10 μm; A 14-34), and the capsules made of polystyrene and covered by a foam absorber (R 140-170 μm; δ 5-10 μm; A 14-34, foam absorber δ 150 μm) - Laser Greenhouse [4].
