Abstract：
When charged particle beams traverse in an accelerating structure, the excited wake fields may dilute the beam energy spread and emittance. In order to estimate the wake field effects on the beam dynamics properly, it is very important to calculate the wake fields precisely. In this paper, the calculation methods of the short range, middle long range and super long range wake fields in constant gradient structures are systematically studied, and the expression of the super long range longitudinal wake field is first given. In addition, the wake fields for the BEPCⅡ Linac's disk-loaded structures are calculated by using analytical methods and various computer codes, the consistency and some deviations of the results obtained by different calculation methods are also discussed.
