DESCRIPTION:Speakers: Konstantin Ten (LIH SB RAS)\nAt fast acceleration of
  metals\, a cloud of microparticles (dust cloud) appears in front of the s
 urface. Work on the study of these processes using Synchrotron Radiation (
 SR) was carried out at the Budker Institute of Nuclear Physics (Novosibirs
 k) [1\,2].   \nIn this work\, the particle flux from shock-loaded tin was 
 recorded using X-ray radiography\, but also synchronously with another 4-c
 hannel Photon Doppler Velocimetry (PDV) laser complex and piezoelectric se
 nsors.   \nThe use of piezosensors and laser complexes PDV is widely used 
 due to the availability and simplicity of obtaining information on the dyn
 amic flows of microparticles. It is advisable to use these techniques in c
 onjunction with other techniques that can evaluate mass and flow rates. Th
 e use of SR radiography is an ideal complement to them. Comparison of data
  on the flow of microparticles (speed and mass distributions) with the mag
 nitude of the signal from the piezoelectric sensor makes it possible to in
 dependently calibrate the sensor readings. The simultaneous use of modern 
 techniques has allowed not only to measure the mass distribution along the
  cloud\, but also significantly increase the reliability of the measured v
 alues.   \nThe flows of microparticles from grooves (roughnesses) with siz
 es from Rz4 to Rz80 made on the surface of tin were investigated. The shoc
 k wave was created by pressed octogen. The data obtained are necessary for
  the numerical simulation of particle ejection processes.   \n  \n1\\. K.A
