Synchrotron radiation (SR) is an important tool not only for basic research, but also for engineering and industry-oriented research and development.
For this purpose, an SR facility project has been proposed at Nagoya University since 1991. In the meantime, the Aichi Prefectural government has been
planning a new research and development complex “Knowledge Hub” for industries in the Central area of Japan and the SR facility proposed at Nagoya
University has been considered to be one of the leading facilities for “Knowledge Hub.” Therefore, the prefecture, industries, universities, and research
institute in the Aichi area are working together to realize this plan.

Accelerators & Beamlines
The key facility of the plan is a compact electron storage ring, which is able to supply hard X-rays. The SR facility,
consisting of accelerators, beamlines, peripheral equipments and housing, has been designed at the Nagoya University
Synchrotron Radiation Research Center. The configuration of NSSR (Nagoya University Small Synchrotron Radiation
Ring) is based on the Triple Bend with twelve bending magnets. Eight of them are normal conducting magnets of 1.4 T
and four of them are 5 T superconducting magnets (superbends), respectively. The bending angle of them is 12 degrees
and two or three hard X-ray beamlines can be constructed at each superbend, so that more than 10 hard X-ray beamlines
can be constructed in our facility. The number of beamlines from normal conducting bending magnets is more than 16.
In addition, we will install an undulator or a wiggler in straight sections.
