Abstract. The paper deals with a theoretical description of the equilibrium orbit manipulations during the particles injection and extraction in synchrotrons. Some original formulae for calculation of the necessary bump magnets strengths are derived. The traditional three bump systems are considered in the general case of arbitrary located bumpers and beam position monitors. This sheme is further improved considering the case of local orbit distortion with an aditional condition to have zero (or only other fixed) slope of the orbit in the septum/kicker.
