摘要 利用电子轨迹跟踪方法对微型轫致辐射X射线光源的一个关键部件———扰动器进行了设计研究。分析了扰动器工作原理,使用CST电磁工作室设计了扰动器的磁场分布,并计算了在此磁场分布下电子的注入效果与扰动器中心位置的关系。结果表明:扰动器的幅向中心位置越靠近电子跨越中心轨道的位置,电子注入后的振幅越小,但同时所需要的磁场强度越大。最后分析了该扰动器注入的横向、纵向接受度,其具有3mm×0.23mrad的横向接受度和0.1%的能量接受度。 Using electron trace program and CST electromagnetic studio,the paper investigated a key component of mini bremsstrahlung X-ray source,perturbator,designed the distribution of the perturbator magnetic field,and studied its effect on the electron trajectory when the perturbator was placed in different angular positions.When the angular position of the perturbator is close to the position where the electrons cross the center trajectory,the amplitude of the electron after being captured is smallest,but the strength of the magnetic field needed is greatest.Moreover,the analysis on the transverse and longitudinal acceptance shows that the transverse acceptance is 3 mm×0.23 mrad and the energy acceptance is 0.1%.
