    Abstract: In a field emission electron gun including heating means for heating an anode to prevent gas emission from the anode due to bombardment thereof by the electron beam emitted from the cathode, the present invention provides a field emission electron gun including first exhaust means for defining a first chamber including the cathode and for exhausting said chamber to vacuum, and second exhaust means separate from said first exhaust means defining a chamber including said anode heating means for exhausting said chamber to vacuum independently of the first exhaust means. This construction makes it possible to maintain the chamber including the cathode constantly in the high vacuum state.

    Abstract: A fluid-tight container holding active getter and non-sorbable gas at a pressure of at least about one atmosphere, with gas flow passage means through a wall of the container providing communication between the active getter and the container-surrounding environment, and removable closure means for the gas flow passage means. The container may be opened for gas flow communication and exposure of the active getter prior to sealing of a vacuum enclosure in which it is installed, without significant loss or impairment of sorptive capacity of the getter.

    Abstract: Presented is a vacuum pressure ionization gauge of the thermionic type which operates in the medium to high pressure range of the vacuum spectrum. It utilizes the principal of gas ionization by means of bombarding gas molecules by electrons emitted by a heated filament. The positive ions produced are collected to provide a positive ion current which provides a measure of the pressure.

    Abstract: ELECTRONS INJECTED BETWEEN A CYLINDRICAL HOUSING AND A COAXIAL CYLINDRICAL GRID AT A PREDETERMINED ANGULAR MOMENTUM SPIRAL OVER LONG PATHS AROUND THE GRID FOR OPTIMUM IONIZATION OF GAS MOLECULES. A FIRST ELECTROSTATIC FIELD IS ESTABLISHED BETWEEN THE HOUSING AND GRID FOR ACCELERATING IONS TO THE HOUSING AND FOR ESTABLISHING AN OPTIMUM KINETIC ENERGY TO THE ORBITING ELECTRONS. A SECOND ELECTROSTATIC FIELD

    IS INDEPENDENTLY ESTABLISHED BETWEEN THE GRID AND A CONCENTRIC TITANIUM ROD ANODE AT AN OPTIMUM INTENSITY FOR ACCELERATING SPENT ELECTRONS THROUGH THE GRID TO BOMBARD AND SUBLIMATE THE TITANIUM FOR BURYING IONS AND COMBINING WITH ACTIVE GASES.
