NIJI-III Compact Superconducting Electron Storage Ring

The NIJI-III is a compact superconducting electron storage ring for industrial applications. Features of the ring include four strongly curved large-bore superconducting bending magnets utilizing quadrupole coils with a circular cross section surrounded by an air core and a cold bore. The circumference of the ring is 15.54 m with a critical wavelength of 13 A. Development of the NIJI-III is near completion. This report examines the design and performance of the NIJI-III.
