PURPOSE:To obtain the titled tube of low cost and high quality by a method wherein a discharge path fine tube forming a discharge path is made of silicon carbide. CONSTITUTION:The fine tube made of silicon carbide forms a discharge path between the cathode 11 and the anode connected via encapsulating trays 2 and 3 respectively. Heat dissipating fins 6 are bonded to the outer periphery of the tube 1, and the heat evolving in the encapsulating trays 2, 3, and 7 and the anode 5 is dissipated via fins 6 by the air fed in from a fan not illustrated. A cathode valve 4 includes the cathode 11 and contains argon gas. Besides, a return path 9 for the argon gas connects the valve 4 with an anode valve 8. |
