Abstract
The paper presents a comparison of the results of numerical simulations of the shock wave (SW) produced inside a stainless steel plate by a powerful pulsed stream of fast ions generated in a dense plasma focus device with its experimental observations. A SW was detected for the first time in a materials science experiment directly by means of multiframe nanosecond laser interferometry. This was visualized in experiments with the PF-1000 facility after the SW went out at the rear side of the thin stainless steel plate into the residual gas atmosphere. In particular, the pressure amplitude of the SW measured by the interferometric method was 16 GPa. The observed value is in good agreement with the results of numerical simulations of the SW pressure amplitude.
