Emission Characteristics of a Barrier Discharge in an Argon-Freon-Water Vapor Mixture in the UV-VUV Spectral Range

摘要

Optical characteristics of an ArCl~*-OH~* lamp excited by a nanosecond barrier discharge are studied. This discharge is a source of the ArCl (B → X), Cl_2~* (D' → A'), and OH(A → X) molecular band emission with peaks at 175, 258, and 309 nm, respectively. The intensity of the barrier discharge plasma radiation is optimized as a function of the CCl_4 vapor partial pressure at p(Ar) = 24 kPa and p(H_2O) = 10-20 Pa.
