  • The flash X-ray radiography is an important diagnostic tool for the ejecta from shocked metal surface. The influence of metal surface characteristics on the ejecta is a main aspect of numerical simulations and experiments on ejecta phenomena from shocked metal surface. A commercial flash X-ray tube, an X-ray camera and high accuracy synchronization timing system were used to establish a system of ejecta diagnosis. The radiographs of ejecta from the tin targets with different depths of grooves were captured and analyzed. The experimental results showed that (1) the mass ejection of tin targets with grooves presented the quasi-multilayer in vacuum; (2) the zone width and ejecta mass increased with the depth of target grooves in vacuum; (3) the region width and ejecta mass decreased as in gas pressure of 0.1 MPa.
