Quantitative data on micro-spall fragments production from metals melted on shock or release are sparse because of diagnostic limitations. In this study, a new diagnostic technology Asay-F-Window was designed, and the mass-velocity distribution of micro-spall fragments was presented. By comparing the measured results of Asay-F-Window with those of piezoelectric pins, the reliability of Asay-F-Window technique was evaluated.

In this paper, Asay-F-window diagnostic technology for high density and large mass ejecta measurement is designed. By Asay-F-window technology, the mass and the density-velocity distribution of ejecta from Pb surface are presented. The difference in ejecta between below and above Pb melting pressure is particularly studied. Moreover, the physical causation inducing the ejecting difference is well explained through theory analysis.
