Design of perturbator for mini bremsstrahlung X-ray source

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 mm0.23 mrad andthe energy acceptance is 0.1%.
