  • Patent number: 11383105
    Abstract: A particle beam transport apparatus includes a vacuum duct, at least one magnet controller, and a scanning magnet. The vacuum duct is configured such that a particle beam advances through the vacuum duct. The magnet controller is disposed around a bent portion of the vacuum duct and is configured to control an advancing direction or shape of the particle beam. The scanning magnet is disposed on the downstream side of the magnet controller in the advancing direction and is configured to scan the particle beam by deflecting each bunch of the particle beam. The magnet controller includes a deflection magnet configured to deflect the advancing direction of the particle beam along the bent portion and a quadrupole magnet configured to converge the particle beam. The deflection magnet and the quadrupole magnet constitute a combined-function magnet arranged at the same point in the advancing direction.

  • Patent number: 10881881
    Abstract: A rotary irradiation apparatus of an embodiment comprises: a rotating gantry; a superconducting electromagnet being installed in the rotating gantry and forming at least one of a deflecting magnetic field that deflects a trajectory of a charged particle beam and a convergent magnetic field that converges the charged particle beam to guide the charged particle beam to an object to be irradiated; a rotating gantry drive unit that drives/rotates the rotating gantry; and a control device that controls the rotating gantry drive unit to rotate and stop the rotating gantry, while the superconducting electromagnet is being excited and the charged particle beam is not irradiated.

  • Patent number: 10256004
    Abstract: A particle-beam control electromagnet capable of shortening a transportation path of a particle beam and an irradiation treatment apparatus which contributes to miniaturization and weight reduction of the rotating gantry supporting this control electromagnet are provided. The electromagnet includes a first superconducting coil group, a second superconducting coil group, and a vacuum vessel. The first superconducting coil group forms at least one of a bending magnetic field and a focus/defocus magnetic field. The second superconducting coil group is placed around the trajectory of the particle beam at the end of the first superconducting coil group and forms correction magnetic fields for correcting the trajectory of the particle beam. The vacuum vessel hermetically houses the first superconducting coil group, the second superconducting coil group, and a cooling medium, and insulates from the outside air.
