Abstract: In a synchrotron radiation light transmission system, a mirror is disposed in a mirror box for reflecting synchrotron radiation light, the mirror box being formed with an incoming opening and an outgoing opening through which the synchrotron radiation light having a horizontally elongated cross section passes. A swinging mechanism supports the mirror so as to allow the synchrotron radiation light entered the mirror box via the incoming opening to be reflected by the mirror and to change a travelling direction in a vertical plane and for swinging the mirror to change a change angle of the travelling direction. The swing axis is on a cross line, or on its extension, between an incidence plane of the synchrotron radiation light and a tangential plane of the mirror at a reflection point and also on an incidence side of the synchrotron radiation light from the reflection point.

Abstract: X-rays transmit through a vacuum duct along an axial direction of the vacuum duct. A plurality of first partition plates are disposed in the vacuum duct. Each of the first partition plates is formed with a first through hole at a central area thereof. The first partition plates divide the inner space of the vacuum duct in the axial direction and define a plurality of partitioned spaces. A plurality of second partition plates are provided each corresponding to each of the first partition plates. The second partition plate is disposed at a certain gap relative to a corresponding one of the first partition plates, each of the second partition plates being formed with a second through hole at a central area thereof, the X-rays transmitting through the vacuum duct passing through the second through hole. A support member connects the second partition plates together and fixes a relative position of the second partition plates.

Abstract: In an electron storage ring apparatus comprising at least two bending magnet units for defining an electron beam orbit of an arc shape, each of the bending magnet units comprises D-shaped upper and lower coil members each of which has an arc-shaped portion. Upper and lower yokes have grooves for entirely receiving the D-shaped upper and the D-shaped lower coil members, respectively.

Abstract: In an electron beam accelerator of the type that electrons are guided into an equilibrium orbit through an inflector and radiant light is generated by accelerating the electrons on the equilibrium orbit, there is provided a drive section for moving the inflector in the directions perpendicular to the plane defined by the equilibrium orbit, and by making use of this drive section the inflector is made to retire from the radiant light. By making the inflector retire, radiant light can be derived also through the position of the inflector, and also, since the inflector is not irradiated by the radiant light, attention of the radiant light caused by lowering of a degree of vacuum can be prevented.
