摘要: 介绍了上海光源直线加速器499.654MHz次谐波聚束器的物理设计、结构、加工、微波测量和试验、运行等的情况。通过2维、3维电磁软件的数值模拟方法对腔型、结构尺寸、电磁参数、调谐范围进行了优化设计，现该腔已经加工完成，并对其进行了电参数测试，结果与物理设计指标吻合很好。在上海光源的束流指标调试过程中，该腔能长期稳定运行。Abstract: This paper presents the physical design，optimization，structure，fabrication，microwave test results and operation of the 499.654 MHz subharmonic buncher for Shanghai Synchrotron Radiation Facility LINAC. The structure optimization of the 499.654 MHz sub-harmonic buncher has been carried out with two-dimensional finite difference method software Superfish and three-dimensional finite element method software HFSS. The optimized buncher has been developed and tested. The measurement results of the buncher agree well with the design values.During the beam target optimization it works very steadily．
