Synchrotron radiation source
 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.
