Target acceleration by sub-microsecond underwater electrical explosions of wire arrays

Experiments of a target accelerated by the shockwaves and water flow generated underwater sub-μs timescale electrical explosion planar wire array are presented. The results this experiment compared with previous [Maler et al., J. Appl. Phys. 129, 034901 (2021)] in which efficient acceleration μs-timescale explosions arrays was obtained. Although less energy is deposited into present experiments, acquires similar even higher velocities to research. This considered be associated density deposition rate, inducing faster radial expansion, and, consequently, generation stronger shockwave behind its front.
