  • Patent number: 8456110
    Abstract: The present invention provides a set of induction accelerating cell for controlling acceleration of a charged particle beam and an induction accelerating device for controlling generation timing of an induced voltage applied by the induction accelerating cell in a synchrotron. The induction accelerating device in a synchrotron includes: an induction accelerating cell that applies an induced voltage; a switching power supply that supplies a pulse voltage to the induction accelerating cell via a transmission line and drives said induction accelerating cell; a DC power supply that supplies electric power to the switching power supply; and an intelligent control device including a pattern generator that generates a gate signal pattern for controlling on/off the switching power supply, and a digital signal processing device that controls on/off a gate master signal that becomes the basis of the gate signal pattern.

  • Publication number: 20100176753
    Abstract: [PROBLEMS] To provide an induction voltage control device (8) capable of accelerating arbitrary charged particles to an arbitrary energy level in synchronization with any magnetic excitation pattern even for an acceleration voltage (9a) of constant voltage by an induction acceleration cell (6) for acceleration and its control method. [MEANS FOR SOLVING PROBLEMS] An induction voltage control device (8) includes: a digital signal processing device (8d) for controlling a variable delay time according to a necessary variable delay time pattern obtained based on a magnetic excitation pattern, an equivalent acceleration voltage value pattern, and a passing signal (7a) of a bunch (3) from a bunch monitor (7); and a pattern generator (8b) for conversion to a gate signal pattern (8a) of a switching power source (5b). The induction voltage control device (8) controls a pulse density of the induction voltage (9) for acceleration per control unit.

  • Patent number: 7223463
    Abstract: A foil is formed on a given substrate, then, peeled off of the substrate and floated on the water surface charged in a tank. The surface level of the water is decreased to contact the foil to a folding plate of a jug substrate and thus, fold the foil at the folding plate in two. The two surfaces of the foil opposing each other are laminated along a foil forming-supporting plate within a laminating region. The thus laminated foil is dried and annealed except the area in the vicinity of the foil forming-supporting plate, and then, cut along the folding plate, a foil acceptor and a supporting plate, to provide a stripping foil which can be supported by itself.
