Abstract
A pair of iron magnetic poles are disposed at the exit of electrons of each of deflecting magnets in an electron storage ring, in which electrons are stored during a certain period of time while being rotated therein, for generating a magnetic field in the direction opposite to that generated by the deflecting magnets. The magnetic field generated by these iron magnetic poles compensates deviations of the orbit of electrons due to the magnetic fringe field of each of the deflecting magnets.
