UV-RADIATION GAS-DISCHARGE ELECTRODE-FREE SOURCE Russian patent published in 1994 - IPC

FIELD: radiation sources. SUBSTANCE: cylindrical glass flask, provided with a window, being transparent for UV-radiation, is placed inside high-frequency reducer, which is used for discharge excitation. Inert gas or inert gases mixture is used as gas filler. Gas absorber is made in form of open ring, formed by a tape of active material. Gas absorber is disposed such a manner, that surface of the ring is perpendicular to the axis of high-frequency reducer. Width of the tape is equal to 0.1 length of the inductor. Length of breakage in the ring is equal to 0.1-0.3 internal diameter of the flask. EFFECT: improved reliability of operation; improved efficiency. 2 dwg
