Investigation of Solid Quasi-Spherical Liner Implosion Using Diagnostic Test Stand and Helical Explosive Magnetic Generator as a Pulsed Power Source

This paper studied the process of implosion of the solid quasi-spherical liner driven by the axial magnetic field generated by the pulsed power source. In the experiment the pulsed power source comprising the helical EMG, the current opening switch and the transmission line provided the current pulse of 13 MA with the rise time of ~10 mus in the liner load. Two radiographic images of the quasi-spherical liner collapsing to the central axis under the effect of the magnetic field forces were obtained at different time moments. The velocity of the inner surface of the quasi-spherical liner at the moment of focusing was ~ 9 km/s. The parameters of the pulsed power source and the image of the imploding quasi-spherical liner obtained experimentally agree well with the calculated values.
