Abstract: A synchrotron radiation light-source apparatus is provided in which the characteristics of synchrotron radiation generated by bending electromagnets can be made uniform, and emittance can be made smaller to increase brightness.

Abstract: A magnetic field apparatus for a particle accelerator having a particle track having curved sections contains several magnetic field-generating windings, and at least one supplemental winding provided for focusing the electrically charged particles. The system does not require pre-accelerators and relatively large particle streams should be capable of being accelerated nevertheless to relatively high energy levels. In the region of at least one of the curved sections of the particle track, an azimuthal guiding field for the particles is generated by the supplemental winding during the acceleration phase. This supplemental winding is designed as an appropriately curved electric conductor arrangement which in part encloses the particle track and which is designed in the manner of a hollow channel open toward the outside. The conductor arrangement is appropriately structured for suppressing eddy currents and carries a current transversely to the particle track.

Abstract: An ion or electron beam is steered or focussed by a circular magnetic field produced by passing a large electrical current through a straight conducting wire, the magnetic field being co-axial with the wire. Annular beams of charged particles coaxial with the straight wire can be focussed onto a circular spot or, depending upon the entry radius of the annular beam and the magnetic field strength, can be induced to follow a looping trajectory. The effect of the steering or focussing system can be enhanced by the provision of a cylindrical conductor which is co-axial with the straight conducting wire such that the particle beam passes between the wire and the cylindrical conductor. The beam steering or focussing systems is applicable to the fields of beam current density intensification, ion implantation, ion separation and free electron lasers.
