ABSTRACT:
A synchrotron radiation apparatus includes a linear accelerator for accelerating an injected electron beam to 20 MeV or less, an energy compaction system for reducing the energy width of an electron beam, an accumulation ring for permitting the high energy electrons output from the energy compaction system to be circulated therein, an injector for injecting high energy electrons into the accumulation ring, a plurality of deflection electromagnets disposed on the respective corner portions of the accumulation ring, for deflecting the high energy electrons from the injector by a preset angle so as to cause the high energy electrons to be circulated in the accumulation ring, and a plurality of beam lines for guiding to a predetermined position, emission light emitted from the accumulation ring when the high energy electrons are circulated in the accumulation ring at a high speed. Each of the deflection electromagnets includes a core having a pair of magnetic poles arranged to face each other in a direction perpendicular to an electron track on which energy electrons are circulated with the electron track disposed therebetween. The deflection electromagnets further include a yoke for integrally coupling the pair of magnetic poles at one-side ends thereof. The core has a "rectangular C"-shaped cross section and integrally formed in a sector shape, and the width of the yoke in a direction perpendicular to the electron track is set larger than the width of the magnetic pole in a direction perpendicular to the electron track.
