Radiographing the high-speed implosion of condensed liner at 35 MA current produced by explosive magnetic generator.

The high-speed implosion of a condensed liner is an efficient method to achieve the state of substance characterized by high energy density, temperature, pressure and substance density. The experimental procedure for radiographing the perturbations growing in the cylindrical aluminum liner having the walls 2 mm thick, which is imploded under the effect of 35 MA pulses produced by high-power explosive magnetic disk generator (DEMG), is described. System shielding the X-ray film situated at a distance of ∼40 cm from HE explosive of ∼ 100 kg in the explosive magnetic generator is described in detail. Specially arranged units having low total thickness equivalent to shield the film ∼15 mm of aluminum were used to provide the necessary protection from damage but still allowed the needed picture contrast. The developed procedure demonstrates the efficiency of EMG in the experiments on pulsed hydrodynamics and high-speed implosion of liners. [ABSTRACT FROM PUBLISHER]
