	In vacuum chamber of SR source, scattered photons provide high intensity flows of photo emitted electrons along the magnetic fields lines. The unperturbed electrons reach the opposite walls. The relativistic bunches influence the trajectories of low energy electrons. These electrons can be trapped by non-uniform magnetic field. The low energy electron distributions change the operating settings of the storage ring. For Siberia-2 case, the low energy electron densities are evaluated both in quadrupole lenses and in superconducting wiggler on 7.5 T field. The qualitative description of the trapped electrons behavior was developed. In calculations, the analitical solution was obtained and used for estimations of the single impact of relativistic bunch.

In vacuum chamber of SR source, scattered photons provide high intensity flows of photo emitted electrons along the magnetic fields lines. The unperturbed electrons reach the opposite walls. The relativistic bunches influence the trajectories of low energy electrons. These electrons can be trapped by non-uniform magnetic field. The low energy electron distributions change the operating settings of the storage ring. For Siberia-2 case, the low energy electron densities are evaluated both in quadrupole lenses and in superconducting wiggler on 7.5 T field. The qualitative description of the trapped electrons behavior was developed. In calculations, the analitical solution was obtained and used for estimations of the single impact of relativistic bunch.
