    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.

    摘要： This invention relates to a turbomolecular vacuum pump (1) of the type having stator blades (10) which are disposed in multistage fashion within a casing (2) and in the axial direction thereof, and rotor blades (11) which are located between the respectively adjacent stator blades (10) and which are disposed on the outer periphery of a rotor (12) situated centrally of the casing (2). A motor rotor (17) is fixed to a rotating member (5) which is formed of the rotor (12) having the rotor blades (11) fixed to its outer periphery, and a motor stator (18) opposite to the motor rotor (17) is arranged to construct the drive mechanism of the rotating member (5). The rotating member (5) is supported at its lower part by a pivot type plain bearing (15). A magnetic bearing (20) is arranged in a manner to oppose between the lower end of the rotor (12) and a supporting member (6) for the rotating member (5).

    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).
