IPC: H01J61/16
Filed: 1978-06-30
Abstract: PURPOSE: To reduce the starting voltage by making the average unevenness of the inner surface of the luminous tube Ra 0.4μ or less to move arc smoothly.  
     CONSTITUTION: 10 mg of sodium and 30 mg of mercury are sealed in the luminous tube 3 made of metal oxide of single crystal or of polycrystal, xenon of 100 Torr up to 150 Trr is also sealed as a starting gas, and the average unevenness of the inner  surface of luminous tube is made Ra 0.4μ or less. when a starting voltage is applied  across the electrodes 10, 11, discharges are started across the electrodes and the inner surface in the neighborhood of these electrodes, one end of arc moves to the central part along the inside of tube. The movement status of arc is influenced by the  unevenness of inner surface. When the inner surface is made smooth, the movement  of becomes smooth too, resulting in a drop of starting voltage.
