Section: 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. The swinging mechanism swings the mirror so that the reflection point of the synchrotron radiation light moves on a reflection plane of the mirror as the mirror swings, and that an incidence angle becomes larger as a distance between a light source of the synchrotron radiation light and the reflection point becomes longer.
