The development technology of Sm2Co17 magnets in China has been improved and sample magnets of three forming-sintering designs have been tested. The test results show that the magnetic properties of Sm2Co17 magnets are improved, and their magnetic moment consistence and stability are fine. The regular magnetic field distribution data and optimized design of China's Sm2Co17 magnets for in-vacuum undulators(IVUs) were obtained and analyzed. Domestic Sm2Co17 magnets will be first installed in the IVUs for the Shanghai protein line station of Shanghai Synchrotron Radiation Facility.%对国产Sm2Co17永磁铁(XG30/20)研制工艺进行了改进,对三种成型-烧结设计所得到的永磁铁样品(65mm×27mm×7.2 mm)进行了测试与分析,结果表明,磁性能有所改善,磁矩一致性和稳定性良好,获得了国产真空波荡器Sm2Co17永磁铁的优化成型-烧结设计和磁场分布规律数据,对永磁铁实验研究结果原理进行了解释.
