Abstract: This paper presents the results of an experimental study of the particle ejection into a low (0.05 atm) vacuum with a narrow (0.2–0.8 mm) rough ($Rz$ = 20–50 $\mu$m) surface of the lead sample under the action of a shock wave of intensity about 17 and 34 GPa. The flow was recorded with a video camera in a microscopic mode with a short laser illumination. Due to the small optical thickness of the dust flow, particle spectra approximately 80% of its height measured from the front of the flow were obtained. It was found that when the lead is in the solid state (17 GPa), s jets consisting of a lot of particles are ejected from the rough surface; when the lead is in the liquid state (34 GPa) a lot of thin (from 7 $\mu$m) microcumulative jets are ejected from the metal surface, which with time decay into particles.
Keywords: shock wave, free surface, ejection of particles, spectrum of particles, microscopic video.
