  • Publication number: 20220210904
    Abstract: An accelerating cavity includes an electrically conductive cylindrical housing and a plurality of cells that are made of a dielectric material and have openings in respective central portions of the cells through which charged particles are allowed to pass. The cells are arranged inside the housing while being aligned in the axial direction of the central axis of the housing, and sandwiched by the housing in the axial direction of the central axis to be immobilized. The housing has grooves provided on portions thereof that support the respective cells and each having a depth that is one fourth of the wavelength of radio frequency waves for the acceleration mode that propagate through the cells.

  • Publication number: 20220130635
    Abstract: Provided is a radiation generation apparatus that can be downsized while improving power efficiency compared with a normal conduction accelerating tube. The radiation generation apparatus includes: an accelerating tube in which an accelerating cavity is defined by a tubular-shaped housing having conductivity and a plurality of cells made of a dielectric material, center openings of the cells being aligned so as to be communicated with each other in a direction in which the cells are arranged in the housing; an RF amplifier that supplies a high-frequency power to the accelerating tube; and an electron gun that emits a charged particle passing through the opening of each of the cells in the accelerating tube.

  • Patent number: 10440809
    Abstract: An RF accelerating cavity includes: a housing having an inner peripheral surface in a tubular shape and conductivity at least on a surface; and accelerating cells inside the housing and each made of a dielectric including, at a central part, an opening through which a charged particle passes. The housing includes a cylindrical barrel portion, with end plates at both ends. The accelerating cells are disposed between the end plates. Each accelerating cell includes: a cylindrical barrel portion having a diameter smaller than an inner diameter of the cylindrical barrel portion of the housing; and a circular disk portion provided inside the cylindrical barrel portion to be fixed to the cylindrical barrel portion, and disposed such that a plate surface is orthogonal to the passing axis of a charged particle, and provided with the opening.

  • Publication number: 20140086387
    Abstract: An object is to emit x-rays having a plurality of different energies and to suppress variations in the energy of the created x-rays. In an x-ray generating apparatus (14) provided in an x-ray inspection apparatus (10), a particle accelerator (20) creates a charged particle beam for generating x-rays having a plurality of different energies, and x-rays are emitted by irradiating a target (22) with the charged particle beam. A single-energy control device (40) controls the particle accelerator (20) for each of the x-rays having different energies on the basis of an x-ray radiation level per unit target current obtained from a measured value of the current flowing in the target (22) and a measured value of the radiation level of x-rays emitted from the target (22), when the target (22) is irradiated with the charged particle beam.

  • Patent number: 8528154
    Abstract: A wiper apparatus is provided that reduces protrusion of a cover at a storage position of a wiper arm, and improves the appearance of the vehicle. A first link between shafts at the lower section of a four-link mechanism is formed by a mounting portion formed on a vehicle body. A second link and a third link at both ends of the first link are formed by link levers. A fourth link L4 between the end portions of the second link and the third link is formed by the proximal end portion of the first wiper arm. A cover is mounted on the proximal end portion of the first wiper arm. One of the pair of link levers, that is, the second link lever arranged closer to the wiper blade has a recess, which is recessed in the direction of a link shaft to prevent contact with the cover.
