Intense electronic excitations and ionizations in electrical discharges in fluids
Project goals
The proposed project is intended to develop a fundamental understanding of a) acoustical features of an underwater discharge using analytical methods and experimental measurements; the dynamic equilibrium at heating, evaporation, dissociation, excitation, ionization, recombination, and condensation during various phases of underwater electrical discharge will be searched; b) high-energy processes in lightning: time and place of birth of runaway electrons will be identified; X-ray observation confirm us that in the long spark /in the lightning a high energy tail of electron energy distribution function is sufficiently populated to allow runaway electron production.

Project results evaluation
Research on spark discharge in water was focused on various aspects of the development of these discharges; the theoretical and experimental results were compared. For spark discharges in air, different methods to facilitate breakdown and extend the gap were tested to enable the production of neutrons and runaway electrons. The results have been presented in journal articles and at meetings.
