| Outline of Final Research Achievements |
Undulators, which generate periodically alternating magnetic fields for undulating electron beams, are an essential device for generating synchrotron radiation. Permanent magnets and electromagnets have been used in conventional undulators, but the use of superconducting materials is expected to significantly improve their performance. In this study, the use of the new material MgB2 has improved the controllability of the periodic magnetic field. As a result, the use of MgB2 suppressed the fluctuation of the peak field strength in rare-earth cuprate superconductors to less than half.
