The study of free supersonic jets showed that the condensation process leads to the Van-der-Waals clusters formation. Supersonic flows clustering leads to a change of the first jet dimensions and to the formation of a secondary structure ("trace"). When the jet is ionized by an electron beam, this structure has a weakly fading glow outside the ionization region. The authors of this work explore the processes leading to the formation of this glow. The condensation influence on the background gas penetration into the jet, the energy exchange effect between jet particles and background particles, and particle lifetime in the "trace's" glow process are studied.
