In designing linac structures for multi-bunch applications the authors are often interested in estimating the effect of relatively weak multi-bunch beam breakup (BBU), due to the somewhat complicated wakefields of detuned structures. This, for example, is the case for the injector linacs of the JLC/NLC linear collider project. Deriving an analytical formula for such a problem is the subject of this report. Note that the more studied multi-bunch BBU problem, i.e. the effect on a bunch train of a single strong mode, the so-called cumulative beam break-up instability, is a somewhat different problem, and one for which the approach presented here is probably not very useful.
