The reverse ballistic configuration to study the impact compression properties of material by means of a light-gas gun was described.In the test a disc-shaped specimen of the test material was mounted in the projectile and caused to undergo planar impact on a stationary diagnostic targets of PMMA.The electromagnetic particle velocity gages embedded in the target were used to obtain the experimental data,and the dynamic states of the test medium was determined by use of the impedance match method.It is helpful for studying the impact compression properties of rocks and other special materials such as inhomogeneous,ferromagnetic,electric,expensive,and hard to machine.
