Abstract:

The comparison of power and spectral characteristics of barrier discharge planar excilamp in binary mixes Kr-Cl₂, Xe-Cl₂, Xe-Br₂, Ar-Cl₂, Kr-Br₂ is carried out. In a row of XeCl-, XeBr-, KrCl-, KrBr-, Cl₂-excilamps, radiant power densities of 39, 30, 19.3, 11.4, and 9.9 mW/cm² have been obtained. The comparison with coaxial barrier discharge excilamps in optimal (from the point of view of radiant power and uniformity of flask filling with microdischarges) conditions has revealed a low efficiency of planar excilamps. In a planar design the distribution of a light flow was nearly uniform over the output window.
