Abstract
A new source of UV radiation (excilamp) based on Kr-KCl vapor-gas mixture excited by a longitudinal high-voltage pulsed-periodic discharge is created. The emission spectrum and time characteristic of the discharge radiation are studied. The B → X transition in the KrCl* excimer molecule (λ = 222 nm) is found to dominate in the radiation spectrum of the source. The dependence of the pulse output power of the lamp on various factors is investigated, and the mechanism of B state formation in the excimer molecule is discussed.
