Abstract:

A new capacitive discharge lamp is created in which the main contribution to the output radiation is due to the iodine atomic emission line at 206 nm. The lamp has an average output power at λ=206 nm reaching 6 W, an efficiency of 8% (with respect to the electric energy supplied to the discharge), and a working life exceeding 1700 h. The results of tests on Escherichia coli and Staphylococcus aureus bacterial cultures reliably confirmed the bactericidal action of radiation of the proposed lamp.
