Abstract

The isothermal cloud chamber has been constructed for investigation of atmospheric conditions for ice crystals formation and the influence of aerosols. The cloud chamber is suitable for simulation of atmospheric conditions where the introduced aerosols of active substances serve as activators. They transform supercooled water aerosols into crystals at temperatures higher that the spontaneous water aerosol crystallization temperature. By counting the formed ice crystals, with the estimation per 1 g of the reagent, ice nucleating properties of some substances (pyrotechnic mixture) have been determined. Determined was also the initial maximum waterness of the supercooled cloud in the chamber and measured the axial temperature gradient.
