The use of titanium metal in vacuum devices

The excellent gettering and gas retention properties of titanium metal make it highly suitable for use in vacuum devices. Tiny receiving tubes made with titanium parts are described which are capable of operating at high cathode emission densities. These high densities reduce the electron transit times and give better high-frequency performance. They permit the use of small electrodes and reduced heater and plate input powers. Vacuum devices made with titanium and ceramic parts can be operated for long periods of time at temperatures up to 700°C.
