Abstract

Concentration of iodine molecules at the outlet of an electric discharge iodine atoms generator was measured using laser-induced fluorescence. Methyl iodine was used as an iodine atom precursor. Fraction of iodine extracted from CH₃I in the discharge generator was about 50%. Optimal mode of operation at which 80-90% of total extracted iodine was in the form of iodine atoms was found. Iodine atom content in the gas flow decreased during transportation down to 20-30% at the point of iodine injection into the oxygen flow. Fraction of power load spent on CH₃I dissociation amounted to ≈3%.
