NON-ELECTRODE HIGH-FREQUENCY HIGH-PRESSURE TUBE Russian patent published in 2011 - IPC H01J61/18 H01J65/04 

FIELD: electricity.

SUBSTANCE: non-electrode high-frequency high-pressure tube includes ball-shaped, cylindrical-shaped burner or burner of other shape, which is located in zone of electromagnetic field of magnetron and made from optically transparent material and filled with inert gas and sulphur. According to invention the following is proposed: additional introduction to the burner of non-electrode high-frequency high-pressure tubes of halogenides of inactive metal in quantity of 0.15 to 0.6 mc mol/cm³; additional introduction to the burner of non-electrode high-frequency high-pressure tubes of metals of group III of Mendeleev's periodic system of elements in quantity of 0.1 to 0.8 mc mol/cm³, additional introduction to the burner of non-electrode high-frequency high-pressure tubes of rare-earth metals in quantity of 0.2 to 0.6 mc mol/cm³, and inert gas pressure is 6.6 to 33.0 kPa.

EFFECT: increasing service life of non-electrode high-frequency high-pressure tubes and reducing their luminous efficiency.
