The effect of the target material and the size of the irradiated volume on the efficiency of ozone synthesis in air under the action of a pulsed electron beam is investigated. Graphite and lead targets were used. The highest concentration of ozone was observed in a chamber without a target, and the highest specific ozone yield without consideration of electron reflection (230 g· (kW· h)-1) was observed in a chamber with a lead target at a minimum air gap (3 cm). The results are explained by the processes of multiple reflection of electrons from elements with a high atomic number at small air gaps compared to the size of the target. Keywords: pulsed electron beam, ozone synthesis, non-equilibrium plasma, electron reflection. DOI: 10.61011/TPL.2023.09.56699.19648
