This study investigated the ejection of microparticle flux (shock-wave dusting) from straight structural joints under strong shock loading from high-power energetic materials (EM). The joints were formed by plates from D16T aluminum alloy and M1 copper, with surface roughness not exceeding 1.6 μm. The process of microparticle injection was registered by synchrotron radiation (SR) pulse radiography from the VEPP-3 collider, which produces steady SR impulses with a duration of 1 ns and a period of 124 ns. A highly sensitive DIMEX detector with an aperture of 40 mm and a spatial resolution of 100 μm was used to record the X-ray shadow. The DIMEX detector is capable of recording an X-ray film of 100 frames. The X-ray shadow recording was performed along the flux of microparticles. To reestimate (calculate) the linear mass of the microparticle flux, the DIMEX detector was calibrated using aluminum and copper foils of different thicknesses. According to the results of measuring the position of the microparticle fluxes, it can be seen that there is a separation into high-density and low-density parts of the flux. The fluxes move at different velocities and as they move, they change their shape (elongate). The linear density distributions of the fluxes are given and their velocities are measured.
