Main results of research are:

1. The threshold processes induced by high-current electron beams in the condensed environments are found and investigated:

   • electric breakdown of dielectrics and semiconductors (ionic crystals, power materials, LED nanoheterostructures);

   • formation of periodic structures of destruction in alkaline and haloid crystals;

   • detonation of brisant explosive of tetranitropentaerythritol (PETN);

   • filamentation and self-focusing of a high-current electron beam in the vacuum diode of the GIV-600 accelerator.

2. Physical models of initiation of explosive decomposition of power materials at excitement are developed by high-current electron beams.

3. The volume electric discharges induced with the help the high-current electron beams in atmospheric air are found and investigated.

4. Processes of a radiating recombination in LED nanoheterostructures of InGaN/GaN at excitement are for the first time studied by high-energy electron beams.

5. Methods of diagnostics and control of materials with application the silnotochnykh of electron beams are developed.
