CAEP XFEL波荡器束线初步物理设计
First design of CAEP XFEL undulator line
摘要
中国工程物理研究院计划开展XFEL光源的研制,主要通过电子束在波荡器中的辐射特性产生硬X射线。根据理论分析和数值模拟,在电子束最高能量可达12 GeV的实际条件下,初步设计了一条间隙可调的真空外波荡器束线,波荡器分为25段,每段长3.86 m,间隙7~10 mm,周期长度25.4 mm,磁场0.636~1.03 T,束线总长120 m左右,辐射光子能量为3~25 keV。
Abstract
XFEL light source which produces hard X-ray from radiation character of electron bunch in undulator will be researched in CAEP. According to theoretical analysis and numerical simulation, an undulator line is designed on the condition that the beam energy can reach 12 GeV at present. The out vacuum undulator line is composed of 25 segments and the length of each segment is 3.86 m. The period length of undulator is 25.4 mm and the peak magnetic field is 0.636-1.03 T, while the gap changes from 7 mm to 10 mm. The total undulator line is about 120 m. The radiation energy designed is from 3 keV to 25 keV.
