DESCRIPTION:Speakers: Ivan Rubtsov (Lavrentyev Institute of Hydrodynamics 
 of the Siberian Branch of the Russian Academy of Sciences)\nA unique insta
 llation\, the only one in the world\, was commissioned - an experimental s
 ynchrotron radiation station at the VEPP-4 accelerator complex: “Investi
 gation of the extreme state of matter” [1]. According to the characteris
 tics of the conducted experiments\, the station has no analogues in the wo
 rld. The new station made it possible to obtain unique in situ data on the
  dynamics of the formation of detonation products of large explosive charg
 es (up to 200 grams) of TNT - RDX.\nThe investigated explosive charges wer
 e cast TG samples (𝜌 ≈1.7 g / cm3) with a diameter of 20\, 30\, 40 an
 d a length of 55 mm. Initiation was carried out by the EDV-1 electric deto
 nator through a plane wave generator (20 mm in diameter) and an intermedia
 te charge of P-84 with a length of 5 mm and a corresponding diameter. Afte
 r the electric detonator\, a contact sensor was installed to stop the reco
 rding of the detector.\nThe experimental data obtained in this work are al
 ready used to take into account the carbon condensation energy behind the 
 chemical reaction zone during detonation of TG charges. They are also impo
 rtant for constructing physical models of detonation and testing early mod
 els of the development of detonation processes.\nIn these experiments\, a 
 scale effect was discovered - a nonlinear dependence of the mass of solid 
 detonation products on the mass of explosives. At small charges (10 -50 gr
 ams)\, the amount of solid detonation products linearly depends on the ini
 tial explosive mass. With large masses of 50 - 150 grams\, a deviation fro
 m the linear dependence is observed. This is a large-scale effect - a devi
 ation from linear dependence.\nThis work was supported by RFBR grants 19-2
