XeCl-, KrCl-, XeBr- and KrBr-excilamps of the barrier discharge with the nanosecond pulse duration of radiation

Results of researches on coaxial one- and two-barrier excilamps based on molecules XeCl^* (λ ∼ 308 nm), KrCl^* (λ ∼ 222 nm), XeBr^* (λ ∼ 282 nm) and KrBr^* (λ ∼ 206 nm) with a short-pulse duration of radiation are given. The peak power of radiation ∼500 W cm^-2 and 4 ns full width at half-maximum (FWHM) are obtained on excitation of a working mixture by the high-voltage pulse generator 'Radan-150' with a nanosecond duration in mixtures with a ratio of rare gas/halogen ≤ 50/1 and total pressure of 500 Torr. The peak power of radiation of the one-barrier KrCl-excilamp excited by the combined Fitch circuit is 1.1 kW cm^-2 at 107 ns FWHM.
