摘要

FIELD: physics.;SUBSTANCE: invention relates to the field of high dynamic pressures and temperatures generation and may be used for chemical reactions, changes in the crystal structure of solids under high pressure and temperature, in particular for producing artificial diamonds (diamond powder), to compress the DT-ice to obtain a neutron source for inertial confinement fusion. The appartus for impact compression process of low density bodies contains the appartus shell 2 and a compressible body 1, installed at the front part of the apparatus shell. The hollow cylinder 5 can be mounted at the apparatus shell, the tail of which may joins a thin-walled hollow cylinder 7 with bar 9. The reactor for the execution of low density bodies impact compression consists of the reactor chamber and two accelerating devices for the apparatuses (cannons), looking toward each other. Inside the reactor chamber a porous layer of a porous metal is installed . The foam metal , tightly packed layer of thin-walled metal tubes, thin-walled boxes layers or cells can be used instead of a porous metal. The summary of the impact compression process of low-density bodies consists of axial compression of each compressed body by solid rear portion of the apparatus shell at frontal collision of two identical apparatuses in the reactor chamber. Thus, there is also impact compression by impact wave and the interference can be used, as well as focusing of reflected from the compressed bodies separation borders and apparatus shells of the impact waves. Also it can be carried out the radial compression of compressible bodies, converging towards the axis of apparatuses by circular liquid or plasma flow, obtained as a result of collision of two hollow cylinders. The interference of two impact waves can be used, resulting from the impact of bars at rear parts of the apparatus shells.;EFFECT: invention allows to increase the final compression , pressure and temperature ratio, while the dynamic compression of low density bodies.;13 cl, 17 dwg
