Abstract
The research investigates two main questions in particle physics and cosmology: the fate of antimatter after the Big Bang and the nature of Dark Matter (DM). It focuses on studying Electric Dipole Moments (EDMs) in particles like protons and deuterons using polarized particle beams in a storage ring. Research and developments have been till now experimentally pursued at the COoler SYnchrotron (COSY) storage ring at Forschungszentrum-Jülich in Germany which has been shut-down at the end of 2023. The next stage involves designing a Prototype Storage Ring (PSR), both all-electric and hybrid (electric and magnetic), with a beam energy of 30-45 MeV and a circumference of around 100 m. The PSR aims to prepare for a final EDM facility, addressing technical uncertainties for measuring a proton EDM. Following the PSR phase, a precision EDM facility with 233 MeV energy and 500 m circumference will seek to significantly enhance the neutron's static EDM limit, potentially leading to significant discoveries.
