Abstract: In this paper,a study of the radiation damage and re-magnetizing utilization of the permanent magnet wiggler used in the Beijing Free Electron Laser facility is reported. For the radiation damaged wiggler,the magnetic strength can be restored to the original value by magnet re magnetization,arrangement optimization and re assembly. The preliminary experimental result shows that the effective lifetime of the re-magnetized wiggler can be longer than the original wiggler under the same beam radiation condition. Also the mechanism of the magnet damage by radiation and the modification method are discussed.
