Emission Characteristics of an Ultraviolet Emitter Based on Mixtures of Krypton with Low-Aggressive Halogen Carriers Pumped by a Barrier Discharge

摘要

The emission characteristics of a pulse-periodic excilamp with three dielectric barriers based on the 222-nm KrCl(X-B) and 248-nm KrF(X-B) emission bands have been investigated. The working gases of the lamp were mixtures of krypton with low-aggressivity halogen carriers (SF_6, CCl_4). Optimal compositions of Kr-SF_6 and Kr-CCl_4 mixtures for obtaining the maximum intensity of the system of 222-nm KrCl(X-B) and 248-nm KrF(X-B) bands have been determined. The results of lamp optimization depending on the parameters of the source of pulse-periodic short-duration barrier discharge are presented.
