Abstract: The aim of the work was to measure the density distribution during shock compression of porous media. For this purpose, experiments were conducted using the VEPP-4 collider (located at the Institute of Nuclear Physics SB RAS). The shock wave was formed by the explosion of a compound based on triaminotrinitrobenzene. Intensity measurements were performed along the styrofoam/fluoroplastics axis after compression by a strong shock wave. The movement of the boundary between styrofoam/fluoroplast and explosion products is visible on X-ray images (dynamic «movie»). To calculate the densities of the compressed substances, calibrations of all the detector channels were carried out. Density distributions of styrofoam/fluoroplastics were obtained under shock wave compression. According to the results of the density distribution there is a monotonous decrease in the intensity of the shock wave in the styrofoam/fluoroplast. The results are consistent with the physical concepts of shock wave propagation in matter. According to the detector data, the dynamics of the shock wave velocity in styrofoam/fluoroplast was also determined.
