北京大学30MeV超导加速器包含3个RF加速单元:自主研发的1.5cell DC-SC(直流-超导)注入器,经过升级的3.5cell DC-SC注入器,以及1.3GHz 2×9cell Telsa型超导加速腔.为充分利用该装置上高品质电子束,计划压缩1.5cell注入器出口电子束用于产生相干THz光,以及压缩2×9cell超导加速腔出口电子束产生红外自由电子激光.通过理论计算及模拟计算相结合设计了一套可变参数磁压缩系统,该系统可以同时满足两个RF加速单元后束团压缩的要求.
Peking University’s 30MeV superconducting accelerator includes three RF accelerators: the independently developed 1.5cell DC-SC injector, the upgraded 3.5cell DC-SC injector, and the 1.3GHz 2 × 9cell Telsa-type super In order to make full use of the device on the high-quality electron beam, plan to compress the 1.5cell injector exit electron beam for generating coherent THz light, and compress the 2 × 9cell superconducting accelerator cavity exit electron beam to generate infrared free electron laser. The theoretical calculation and simulation calculation are combined to design a variable parameter magnetic compression system which can satisfy the requirements of the bunched mass after two RF accelerating units.
