PURPOSE:To optimize the electromagnet arrangement of an accumulation ring for miniaturizing and energy saving, by forming the electromagnet arrangement consisting of superconductive electromagnets in an accumulation ring having rotational symmetry in three phases and using a super conductive acceleration tube. CONSTITUTION:In an accumulation ring, the shape of the ring has rotational symmetry in three phases in relation to the center, while a septum electromagnet 10, a wiggler electromagnet 9 and a superconductive acceleration cavity 8 are arranged respectively in long linear space at three spots. By such a ring form and arrangement of constituent elements, a compact accumulation ring, in which necessary constituent elements are fully arranged without any needless/space, can be obtained. Further, since electronic energy is proportional to a product of a magnetic field made by a deflection electromagnet and an orbital radius, the orbital radius can be reduced while miniaturizing the accumlation ring by making the deflection electromagnet 7 superconductive and heightening the magnetic flield intensity.
