A pulse X-ray diffraction measurement system is established by using a miniaturized flash X-ray source on gas gun loading experimental platform.The system is used to study the microstructure change of LiF crystal lattice under plate shock loading experiments.Single pulse X-ray diffraction images from LiF crystals are obtained under different shock loading pressures.Experimental results show that crystal lattice of LiF is compressed when LiF crystal is loaded along [100]orientation,and the amount of compress...
