In the physics of accelerators and colliders there is one important parameter as “impedance”. Impedance determines the level of the influence of the field induced by the beam in the longitudinal and transverse directions on the beam motion. Knowledge of the impedances is necessary for estimating the conditions for the stability of the beam motion in the designed accelerator. Thus, the main objective at the moment is the calculation of the impedance of each device in the collider for further calculation of their contribution to the general impedance. In the report the physics of the beam motion in an accelerator chamber is considered, the method of calculating the impedance - the method of electro-magnetic simulation through the CST Studio Suit software package is described, an example of the calculation of the impedance for the part of vacuum chamber of the quadrupole magnet, which is a part of the arch of the collider NICA is shown.
