Abstract

Nagoya University has a project to construct a new synchrotron light facility, called Photo‐Science Nanofactory, to develop a wide range research on basic science, industrial applications, life science and environmental engineering in collaboration with universities, research institutes and industries. The key equipment of the facility is a compact electron storage ring, “Nagoya University Small Synchrotron Radiation facility (NSSR),” which is able to supply hard x‐rays. The plan of the specifications is as following. The energy of the stored electron beam is 1.2 GeV. The circumference is 62.4 m. Natural emittance is about 60 nmrad. The configuration of the storage ring is considered based on the Triple Bend Achromat with twelve bending magnets. Eight of them are normal conducting magnets. Four of them are 5T superconducting magnets (super‐bends). The bending angle is 12 degrees and two or three hard x‐ray beam lines can be constructed for each super‐bend. The number of beam lines from normal conducting bending magnets is more than 16. In addition, we will install two undulators in straight sections. The electron beam is injected from a booster synchrotron with the energy of 1.2 GeV as full energy injection. A 50 MeV linac is used as an injector to the booster synchrotron. The top‐up operation is also planned.
