    摘要： An industrial compact synchrotron radiation source with improved vacuum to prolong life-time of a charged particle beam. The synchrotron supplies highly stable, intense synchrotron radiation. In the source, a charged particle beam bending duct (1) forming a vacuum chamber through which the charged particle beam circulates, is encompassed by a bending electromagnet (2). At least one SR guide duct (3) for guiding the radia­tion to the outside extends from the outer circumferential wall (1e) of the bending duct. The SR guide duct is connected through a gate valve (5) to an SR beam line duct (7) for guiding the SR beam to an object to be worked on. A vacuum pump (4) is disposed on the side of the gate valve, close to an orbit (A) of the charged particle beam. The SR guide duct extending from the outer circumferential wall of the bending duct takes the form of a divergent duct which is widened in accordance with a spreading angle (ϑs) of the SR beam travelling through the SR guide duct.

    摘要： Synchrotron radiation is generated when a base of charged particles is bent by a bending magnet. The synchrotron radiation passes down a lead-out duct (3) as the total number of pumps is limited by the size of the apparatus and many pumps are needed in order to achieve a good vacuum. An ion pump (4) has a main magnetic field (13), normally generated by a magnet (12) of the ion pump (4) which controls the behaviour of the electrons in the ion pump (4). However, the leakage magnetic field (14) of the bending magnet effects the ion pump (4), and therefore the ion pump (4) is arranged so that its main magnetic field (13) is aligned with the leakage magnetic field (14) at the ion pump (4), or at least with a main component thereof. In this way, the effect of the leakage magnetic field (14) on the ion pump (4) is reduced. Indeed, it is possible to use the leakage magnetic field (14) as the main magnetic field of the ion pump (4).

    摘要： A synchrotron radiation source and a method of making the same are concerned. An assembly of a beam absorber (1) for synchrotron radiation beams and a piping (2) for cooling the beam absorber (1) is mounted in a charged particle beam duct (5) of a bending section (10) for bending a charged particle beam. Fixed to at least one of straight ducts (8) connectable to the opposite ends of the charged particle beam duct (5) is a piping guide duct (7) through which the beam absorber cooling piping (2) is drawn to the outside, so that the assembly of the beam absorber (1) and beam absorber cooling piping (2) can readily be mounted in the synchrotron radiation source.
