Research Abstract

We have introduced a pair of flash X-ray system with the applied voltage of 300kV in order to study the transient phenomena during the high velocity collision among planetary bodies, and we have tried to construct a new perspective of an impact cratering process by means of these apparatus. Then, we succeeded to observe the impact penetration of a projectile and the crater formation accompanied by this penetration. As a result, we have obtained several new results on the laboratory experiments of the projectile penetration and the crater formation on the porous target, the numerical simulation of the excavation flow during the crater formation, and the observation of the ejecta-expansion from the impact point.
