SPONTANEOUS RADIATION SOURCE Russian patent published in 2006 - IPC H01J61/80 

FIELD: lighting engineering; effective radiation sources operating in ultraviolet and vacuum ultraviolet spectrums.

SUBSTANCE: proposed radiation source has cylindrical coaxial dielectric tubes forming sealed gas-discharge bulb filled with working medium. Electrodes are disposed on outer surface of external tube and on inner surface of internal tube. External electrode is made of solid reflecting semi-cylinder tightly fitted to tube by means of wire turns. Ratio of internal tube diameter D₂ to external tube diameter D₁ is 0.4 < D₂/ D₁ < 0.7. Xenon and krypton can be used as working media.

EFFECT: enhanced radiation power density on irradiated object in short-wave spectrum; enhanced heat-transfer coefficient.
