Girder resonant properties analysis for the “SKIF” synchrotron

Abstract

All magnetic elements that form a closed orbit and focus the beam of charged particles in the accelerator are installed on special precise and stable supports – girders. Like any mechanical system, the girder has its natural frequencies, at which the vibrations coming to it are amplified. To ensure the stability of the charged particle beam, it is important to understand how mechanical vibrations are transmitted from the floor to the magnetic element, since even small perturbations can lead to a worsening in the parameters of the charged particle beam. The article presents the results of experimental seismometric measurements of the girders for magnetic elements of the booster Siberian Circular Photon Source “SKIF”. Their natural frequencies are determined.
