We developed a method to control the systematic background for Electric Dipole Moment searches in all-magnetic storage rings at the level of ≈ 10− 20e ⋅cm for deuterons at beam momentum 970 MeV/c. The method is based on a principle of spin tune modulation in a predictable way and was tested at cooler synchrotron COSY in Forschungszentrum Juelich. Two static solenoids were used as spin rotators. A special scheme of precise spin tune measurements at different spin rotation angles in solenoids allowed to determine the presence of systematic background.
