SCIENTIFIC AND ORGANIZATION STRUCTURE

LABORATORY OF LOW-TEMPERATURE PLASMA

The Laboratory of Low-Temperature Plasma was established in 1980 based on Gas Electronics Group headed by Yu.D. Korolev. At present time the laboratory staff consists of 9, including 1 Doctor of Science, 1 Candidate of Science, 5 scientific researchers, and 2 post-graduates.

Scientific Activities

Investigation of pulsed gas discharges and development on this basis of high-current electronics devices.

The Main Scientific Achievements

The results of investigations devoted to influence of method of electrons initiation on evolution of breakdown were recorded by the State Committee of Inventions (Invention № 365) as discovered regularity of "external ionizing radiation effect on the process of evolution of high-pressure pulsed discharge in highly overvoltage gas gaps".
A new class of volume discharge instabilities related to effect of local enhancement of electric fields, in particular, explosive emission instability resulting in appearance of cathode spot and highly conducting spark gap was discovered and studied.
A conception of non-monotonous potential distribution was suggested and developed in the frames of which it was possible to give compatible interpretation of a number of phenomena accompanying discharge burning in gases at low pressures: the so-called anomalous electron emission, cathode erosion modes, breakdown initiation mechanism, a phenomenon of speedy propagation of ions to anode was proposed and evolved.
A novel direction in studies of low-pressure high-current pulsed discharges with hollow cathode and hollow anode has been developed. The mechanism of discharge formation and current maintenance was substantiated. Various applications of such discharges were proposed.
A new class of high-current commutating devices based on cold cathode low-pressure discharges (the so-called pseudospark discharge switches) presently industrially developed has been built up.
