Studies of the condensation of supersaturated water vapor associated with atmospheric ionization and its accompanying characteristic IR emission

The paper describes the upgraded system for generation of supersaturated H 2O vapor. It was created on the basis of the unique IAO SB RAS stand. The system controls the thermodynamic parameters of vapor under low pressure. Besides, the method for monitoring kinetics of H 2O monomer concentration was verified. The droplet formation technique was tested through absorption and scattering of laser radiation. We elaborated the method for selecting the generated aerosol by size when pressure goes down and when supersaturated water vapor is under the action of an electron beam.
