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].
