Central Japan synchrotron radiation research facility project

Nagoya University has proposed a project to a new small synchrotron radiation facility for hard X-rays since 1991. The key equipment of the facility is a compact electron storage ring which can supply hard X-rays. The specifications of the project are as follows: the energy of the stored electron beam is 1.2 GeV, the circumference 62.4 m, and natural emittance 53 nm-rad. The configuration of the storage ring is based on the triple bend cell with twelve bending magnets. Eight of them are normal conducting magnets of 1.4 T, while four of them are superconducting ones (superbends) of 5 T. The bending angle of the superbend is 12 degrees and two or three hard X-ray beamlines can be constructed for each superbend. The electron beam is injected from a booster synchrotron with the energy of 1.2 GeV as full energy injection for the top-up operation. A 50 MeV linac is used as an injector to the booster synchrotron. The project has now developed to 'Central Japan Synchrotron Radiation Research Facility' as the principal facility of the project of Aichi prefecture 'Knowledge Hub' to establish a new research center for technological innovation.
