A unique installation, the only one in the world, was commissioned - an experimental synchrotron radiation station at the VEPP-4 accelerator complex: “Investigation of the extreme state of matter” [1]. According to the characteristics of the conducted experiments, the station has no analogues in the world. The new station made it possible to obtain unique in situ data on the dynamics of the formation of detonation products of large explosive charges (up to 200 grams) of TNT - RDX. The investigated explosive charges were cast TG samples (𝜌𝜌 ≈1.7 g / cm3) with a diameter of 20, 30, 40 and a length of 55 mm. Initiation was carried out by the EDV-1 electric detonator through a plane wave generator (20 mm in diameter) and an intermediate charge of P-84 with a length of 5 mm and a corresponding diameter. After the electric detonator, a contact sensor was installed to stop the recording of the detector. The experimental data obtained in this work are already used to take into account the carbon condensation energy behind the chemical reaction zone during detonation of TG charges. They are also important for constructing physical models of detonation and testing early models of the development of detonation processes. In 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 grams), the amount of solid detonation products linearly depends on the initial explosive mass. With large masses of 50 - 150 grams, a deviation from the linear dependence is observed. This is a large-scale effect - a deviation from linear dependence.
