Abstract:
An electron beam-irradiating reaction apparatus comprising:an electron beam irradiation device for generating an electron beam, said electron beam irradiation device having an electron beam release window for allowing emission of the electron beam; a metal window foil extending across said electron beam release window so as to maintain a vacuum within said electron beam irradiation device; an electron beam reaction device for containing a gas to be irradiated by the electron beam, said electron beam reaction device having an electron beam receiving window arranged so that the electron beam generated by said electron beam irradiation device is received by said electron beam reaction device via said electron beam receiving window, said electron beam irradiation device and said electron beam reaction device being independently supported and not rigidly connected to each other; a cooling gas nozzle assembly including a blow opening arranged to blow cooling gas against said metal window foil; and a flexible hermetic sealing member between said electron beam irradiation device and said electron beam reaction device, and arranged to prevent leakage of the cooling gas and the gas to be irradiated.
