    Abstract: PROBLEM TO BE SOLVED: To provide an electron acceleration method facilitating maintenance of an electron beam device, and increasing the degree of vacuum in a vacuum chamber without operating a vacuum pump for continuous exhaust.
    SOLUTION: This electron acceleration method is structured such that an electron beam emission window 24 is airtightly brazed to a vacuum chamber 46 in a place controlled into a clean air environment; the vacuum chamber 46 sustainably keeping vacuum without operating the vacuum pump for continuous exhaust is arranged by welding or bonding and connecting to be sealed; electrons are generated by an electron generator 31 positioned within the vacuum chamber; the electron generator is surrounded by a housing 30; the housing is formed with an opening between the electron generator and the electron beam emission window for allowing electrons to be accelerated from the electron generator 31 to the outside of the electron beam emission window 24 in an electron beam when a voltage is applied between the housing and the electron beam emission window 24; molecules in the vacuum chamber is ionized; and the ionized molecules in the vacuum chamber are captured to increase the degree of vacuum in the vacuum chamber.

    Abstract: PROBLEM TO BE SOLVED: To approximately equalize an electron beam emitted from a window in the vicinity of both ends of a an emission component with one emitted from a window in the vicinity of the center of the emission component and normally output both beams.
    SOLUTION: The electron beam tube is equipped with a vacuum container 1, electron generation components 41 and 42, an electric field generation component 3 and the emission component 2 which is formed on an end face of the vacuum container 1 and has windows 21 and 22 transmitting the electron beam. The electron beam tube is characterized in that it has a first electron beam control component 31 which is equipped with the electron generation components 41 and 42 and is so constituted that one end of the electric field generation component 3 is connected to the emission component 2 in the vacuum container 1 and the other end of the component 3 extends to above the outer periphery of the electron generation components 41 and 42 and a second plate electron beam control component 33 which is so constituted that one end of it is connected to the space between the windows 21 and 22 corresponding to the electron generation components 41 and 42 respectively of the emission component 2 in the first electron beam control component 31 and the other end of the component 33 extends to the upper part between the electron generation components 41 and 42 severally.
