Title:     Uncover Periodicities in Detector Signals at the Cooler Synchrotron COSY

Abstract: The Cooler Synchrotron COSY located at Forschungszentrum Juelich provides polarized and unpolarized protons and deuterons in a momentum range of 0.3 - 3.7 GeV. Since 2011, the JEDI (Juelich Electric Dipole moment Investigations) collaboration aims to measure directly the Electric Dipole Moment (EDM) of deuterons for the first time by observing the influence of the EDM on the spin motion in the accelerator. EDMs of elementary charged particles are candidates for CP violation, which could help explain the matter-antimatter asymmetry in the universe. Precision experiments like the search for EDMs in storage rings require precise knowledge of systematics. The main observable of the experiment is the frequency of the oscillating vertical polarization component of the bunched beam. However, tiny disturbances of the beam could interfere and change the oscillation frequency. In this talk, the detection of periodicities in the detector signals using neural networks and an overview of recent Machine Learning activities at COSY and the JEDI collaboration, supporting the detection of sources of systematics and improving the sensitivity, will be presented.
