Abstract: The present invention relates to an electron beam-irradiating reaction apparatus for irradiating a desired object to be treated, such as an exhaust gas, with an electron beam. Conventionally, a scanning tube of an electron beam irradiation device and a reaction device-for receiving the electron beam are rigidly connected. Therefore, excessive stress is applied to a connecting portion between the scanning tube and the reaction device and not only leakage of gas from the connecting portion, but also breakage of a metal window foil provided at an end portion of the scanning tube are likely to occur. In the present invention, to solve such problems, a flexible hermetic sealing member 23 is provided between a portion around the end portion of the scanning tube 12 and a peripheral edge 18a of an electron beam receiving window in a side wall of an electron beam reaction device 18.

Abstract: An electron accelerator includes a vacuum chamber having an electron beam exit window. The exit window is formed of metallic foil bonded in metal to metal contact with the vacuum chamber to provide a gas tight seal therebetween. The exit window is less than about 12.5 microns thick. The vacuum chamber is hermetically sealed to preserve a permanent self-sustained vacuum therein. An electron generator is positioned within the vacuum chamber for generating electrons. A housing surrounds the electron generator. The housing has an electron permeable region formed in the housing between the electron generator and the exit window for allowing electrons to accelerate from the electron generator out the exit window in an electron beam when a voltage potential is applied between the housing and the exit window.
