A new concept of synchrotron radiation (SR) sources with ring-shaped high-Tc superconducting bulk (bulk ring) magnets have been proposed at the SPring-8, a SR facility in Japan. During the proof-of-principle experiments, it was found that the magnetic field generated by the bulk ring gradually decreased, due to mechanical damages in the bulk ring. In order to improve the mechanical property of the bulk ring toward realization of this concept, two methods of reinforcement, i.e., resin impregnation and iron ribbing, were proposed. The effects of these methods were investigated with four bulk ring samples and it was found that combination of the two methods significantly improved the mechanical property.
