  • Patent number: 4931744
    Abstract: A synchrotron radiation source and a method of making the same. As assembly of a beam absorber for absorbing synchrotron radiation beams and a piping for cooling the beam absorber is mounted in a charged particle beam duct of a bending section of the synchrotron radiation source for bending a charged particle beam. Fixed to at least one straight duct that is connectable to either of the opposite ends of the charged particle beam duch is a piping guide duct through which the beam absorber cooling piping is drawn to the outside, so that the assembly of the beam absorber and the beam absorber cooling piping can readily be mounted in the synchrotron radiation source.

  • Patent number: 4853640
    Abstract: An industrial compact synchrotron radiation source which can improve vacuum evacuation performance to prolong life-time of a charged particle beam and supply highly intensive stable synchrotron radiation. In the source, a charged particle beam bending duct forming a vacuum chamber through which the charged particle beam circulates is encompassed by a bending electromagnet, and at least one SR guide duct for guiding the radiation to outside extends from the outer circumferential wall of the bending duct. The SR guide duct is connected through a gate valve to an SR beam line duct for guiding the SR beam to an object to be worked and a vacuum pump is disposed on the side, close to an orbit of the charged particle beam, of the gate valve. The SR guide duct extending from the outer circumferential wall of the bending duct takes a form of a divergent duct which is widened in accordance with a spreading angle of the SR beam traveling through the SR guide duct.
