The group of electrophysical technologies

The Electrophysical technologies group has arisen in laboratory nowadays the late corresponding member of Russian Academy of Sciences Ju.A. Kotov and originally participated in number working out high current electron accelerators and bremsstrahlung generators with the intermediate inductive energy storage and electrically explosive wire («VIRA-1,5», «VIRA-1,5M») as well the plasma opening switch «VIRA-2P».

Since 1996 a line of frequency nanosecond electron accelerators type URT with the semiconductor opening switch and thyratron – magnetically circuit of energy compression developed which were placed in the research institutions in Russia (IFCE RAS and UrFU) and Japan (JAERI) and also in an industrial technological line of radiating oxidation of polyethylene (Joint-Stock Company "NIIHIT-2", Saratov).

The group makes the investigations of nanosecond electron beam applications for chemical reactions, sterilization of the medical tool and foodstuff, water treating, nanopowder production and others.

In 1997 the method of radiochemical sterilization of the packed products was found, which consist in synergetic effect both of radiation and ozone that formed under electron beam irradiation (RU Patent № 2163144).

In 1998 the method of antimicrobic treatment of liquids using nanosecond high voltage pulses was created (RU № 2316989).

In 1999 the ceramic cathode was created using a mixture of oxide nanopowder and a micron powder of metal that have uniform electron beam density distribution and high lifetime (RU Patents № 2158982 and № 2191488).

In 2007 the method (RU Patent №2353573) and installation for production nanopowders of metals, oxide and compound was created using the target evaporation by a pulsed electron beam in a low pressure gas and a cryogenic crystallizer condensation which were placed in Russia and Republic Korea (KAERI). This patent award the Diploma of Federal Agency in intellectual property, patents and trade marks in a nomination "100 best inventions of Russia” in 2008.
