Vapor condensation under ionizing effects

The ionizing effects of an electron beam and static electricity on the water vapor condensation in different conditions of supersaturation have been studied using an experimental setup designed on the basis of an atmospheric optical cell, which is a tube of 0.7 m in inner diameter and 112 m in length made of stainless steel. In this setup, water vapor is supersaturated through pressure release from the working chamber of a comparatively small volume to the vacuumized chamber of a larger volume, like in the second type of Wilson chamber; this allows us to achieve significant degrees of water vapor supersaturation. The experiments carried out show a pronounced dependence of behavior of a signal, caused by radiation scattered by droplets formed in expansion of the vapor-air mixture, on factors affecting the mixture ionization. The results point to a significant dependence of the droplet-formation dynamics on the degree of air ionization.
