Emission spectra of dense Kr + SF 6 gas mixtures with different composition excited by a pulsed beam of fast electrons are measured. The electron energy is 150 keV, and the amplitude and duration of a beam current pulse are 5 A and 5 ns. The composition of gas mixtures was Kr (190-1900) Torr and SF 6 (0.1-1.0) Torr. The efficiency of formation of excimer Kr 2 F* molecules was found to be high in dense (~1 atm) Kr-SF 6 mixtures with a low SF 6 donor content. The luminescence times and quenching constants of broadband emission of the Kr 2 F* molecule (λ max = 404.7 nm) by components of a gas mixture are measured.
