RFNC-VNIITF Activities

Currently RFNC-VNIITF is one of the largest research institutions both in nuclear weapons development and in fundamental and applied research in such areas as:

•    properties of matter in a wide range of pressure and temperature;
•    equilibrium and non-equilibrium phase transitions;
•    kinetics of detonation;
•    thermonuclear reactions;
•    plasma physics;
•    turbulent mixing;
•    strength and failure models;
•    hydrodynamics;
•    laser physics;
•    inertial confinement fusion;
•    physics of laser beam interaction with matter;
•    astrophysics (stellar processes, bursts of supernovas); and
•    numerical simulation.

Institute structure is favorable for theoretical studies, development of physical models for complex phenomena and processes. RFNC-VNIITF scientists got unique results in fundamental research, in particular with the help of processes occurring in the nuclear explosions. This includes experimental data on thermonuclear detonation of cylindrical systems, on conditions of thermonuclear ignition in extreme spherical systems, shock compression of some substances under gigabar pressures (by 2-3 orders of magnitude higher than in laboratory experiments with HE). Influence of shell electron atom structure on thermodynamic properties and optical transparency of substances at high temperature was discovered, and unique data were obtained on turbulent mixing of matter in dynamic processes. These results are fundamental for state-of-the-art high energy density physics.
Very important results were also obtained in such fields as:

–    research of inertial confinement fusion,
–    impact of powerful laser beams on matter,
–    laboratory x-ray lasers,
–    high-speed collision of bodies,
–    description of high-intensity magnetic processes, etc.

RFNC-VNIITF gives special emphasis to research of cumulation phenomena like implosion, convergence of shock waves and shells, which lead to essential growth of internal and/or kinetic energy density essentially. Major contribution to the research into cumulation processes was made by academician Evgeny Zababakhin. Currently areas where such processes take place keep growing in number and include, for example, inertial confinement fusion, research of matter properties in extreme states, application of cumulative jets in industry. This is also important for catastrophic natural phenomena: avalanches, tsunami, star births, bursts of supernovas, etc.
