Freon destruction in atmosphere by relativistic electron beam

The lise of relativistic electron beam (REB) to initiate freon destruction in the dissociative electron allachment reactions at the height less than that of the ozone layer (10 – 15 km) is proposed. The REB advantages are the lower electron temperature of the beam excited plasma (what results in higher reaction rate), the high efficiency of ionization energy cost (up to 50%), and also the high efficiency of modern accelerators. The recent experimental results support the supposition of high efficiency, which at pressure of 760 Torr and CFC mixing ratio of 25–650 ppm may be of 40–100 eV/molecule. The REB power needed for cleaning the atmosphere volume of 10*100*10 km should be of order of 1 – 10 MW. considering the reaction energy cost of order of 100 eV/mol and the mean CFC concentration recovery time of order of 3 months, may be taken as acceptable. The proposed variant REB atmosphere excitation may be part of broader program of active atmosphere experiments.
