Abstract:
A synchrotron radiation light transmission system, comprising:a mirror box formed with an incoming opening and an outgoing opening through which synchrotron radiation light having a horizontally elongated cross section passes;a mirror disposed in said mirror box for reflecting the synchrotron radiation light; anda swinging mechanism for supporting said mirror so as to allow the synchrotron radiation light entering said mirror box via the incoming opening to be reflected by said mirror and to change a travelling direction in a vertical plane and for swinging said mirror to change an angle of the travelling direction, wherein a 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 said mirror at a reflection point and also on an incidence side of the synchrotron radiation light from the reflection point, the reflection point of the synchrotron radiation light moves on a reflection plane of said mirror as said mirror swings, and said mirror is swung so that an incidence angle becomes larger as a distance between a light source of the synchrotron radiation light and the reflection point becomes longer.
