Abstract
PURPOSE: To produce a photoelectron booster tube of less current leakage and noise and high photoelectric sensitivity and secondary emission rate by gradually sending alkaline metal into a photoelectron booster tube through a thin tube by heating an alkaline metal container.
CONSTITUTION: After evacuating the air from a booster tube 1 through an exhaust tube 2, an alkaline pellet 5 is heated with a high-frequency heater 6 to produce an alkaline metal by reduction. After keeping the booster tube 1 at a high temperature and the seald alkaline metal container 3 at a higher temperature than that of the booster tube 1 in a furnace until the photoelectric sensitivity of the photoelectron booster tube reach a fixed level, then a thin tube 4 is cut and sealed to separate the container 3. After further keeping the photoelectron booster tube 1 at a fixed temperature for a fixed time period to discharge excessive alkaline metal, the photoelectron booster tube 1 is cooled down and the exhaust tube 2 is cut and sealed.
