Abstract:
The jet structure from metal surface initiated by shock wave was investigated by small angle X-ray scattering (SAXS) technique for the first time. In these experiments used synchrotron radiation from the colliders VEPP-4. The beamlines 0-b at VEPP-3 and 8-b at VEPP-4 were used. These technique enables reliable detection of metal nanoparticles of 4 - 200 nm size with exposure time 73 ps (at VEPP-4) for one frame and interval 125 ns. It was found that jet from tin and tantalum foils impacted by pressed HMX gives a strong SAXS signal. This means that dust in jet contain nanoparticles. SAXS curve processing gives the nanoparticles size - about 100 nm. The flow of micro- and nanoparticles was about 4% by weight. The SAXS signal decreases with the usage of a less strong high explosive (plasticized PETN). It was found for the first time that the dust in jet has fine structure of density distribution which changes with time.
