| 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 undulaor 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. |
