Synchrotron Radiation Study of Shock-Induced Ejecta

When studying the process of shock-induced ejecta, in particular when particle jets move in a gas or are caused by several shock waves, it is necessary to obtain experimental data on the time history of density in these jets starting from the moment of shock-wave arrival at the free surface of the sample. In this work, such measurements were performed using flash radiography with synchrotron radiation. In the experiments, one or two successive shock waves with a pressure of $${\approx}40$$ GPa arrived at the free surface of tin samples with a roughness Rz of 5, 20, and 60. Shock unloading occurred in vacuum or gas (air, helium, nitrogen) at initial pressures of $$1{-}8$$ atm. The paper presents the experimental setups and experimental data on the density dynamics in ejecta formed after the arrival of one and two successive shock waves at the free surface of samples in vacuum and gas media.

Abstract

When studying the process of shock-induced ejecta, in particular when particle jets move in a gas or are caused by several shock waves, it is necessary to obtain experimental data on the time history of density in these jets starting from the moment of shock-wave arrival at the free surface of the sample. In this work, such measurements were performed using flash radiography with synchrotron radiation. In the experiments, one or two successive shock waves with a pressure of $${\approx}40$$ GPa arrived at the free surface of tin samples with a roughness Rz of 5, 20, and 60. Shock unloading occurred in vacuum or gas (air, helium, nitrogen) at initial pressures of $$1{-}8$$ atm. The paper presents the experimental setups and experimental data on the density dynamics in ejecta formed after the arrival of one and two successive shock waves at the free surface of samples in vacuum and gas media.
