| Abstract: | Experimental, numerical, and theoretical investigations are made of a gas flow generated by a pulsed high-current discharge
in an axisymmetric cavity bounded by a spherical lens adjacent to a flat plate. It is shown that the shock wave forming in
the discharge and converging toward the axis is accelerated and amplified as it converges. The amplitude of the shock wave
increases faster than does that of a spherical converging shock wave.
