Main topics discussed are: online determination of spin tune and in-plane polarization, how to achieve large spin coherence times, and phase-lock feedback for synchronizing spin precession and RF devices. The $R\&D$ is primarily motivated by precision experiments on Electric Dipole Moments (EDMs) of charged particles in storage rings, including feasibility studies and a first deuteron EDM measurement at COSY.}, month = {Mar}, date = {2025-03-10}, organization = {Polarized Ion Sources and Beams at EIC, Stony Brook (USA), 10 Mar 2025 - 12 Mar 2025}, subtyp = {Invited}, cin = {IKP-2}, cid = {I:(DE-Juel1)IKP-2-20111104}, pnm = {612 - Cosmic Matter in the Laboratory (POF4-612) / srEDM - Search for electric dipole moments using storage rings (694340)}, pid = {G:(DE-HGF)POF4-612 / G:(EU-Grant)694340}, experiment = {EXP:(DE-Juel1)JEDI-20170712}, typ = {PUB:(DE-HGF)6}, doi = {10.34734/FZJ-2025-02293}, url = {https://juser.fz-juelich.de/record/1041519}, }
