Feasibility studies of the stochastic cooling system in the proton storage ring EDM experiment

This study explores the feasibility of implementing stochastic cooling in the proposed proton electric dipole moment (pEDM) storage ring to be constructed at Brookhaven National Laboratory. Investigating fundamental physics phenomena, such as the electric dipole moment (EDM) of protons, demands highly precise experimental setups. In such precision experiments, intra-beam scattering (IBS) causes emittance growth, which degrades beam quality and limits the spin coherence time (SCT), a key parameter for sensitive EDM detection. The integration of a stochastic cooling system for stored polarized proton beams offers a potential solution by mitigating the effects of IBS, suppressing emittance growth, stabilizing beam dynamics, and enhancing the overall efficiency of the storage ring. This paper examines the feasibility of incorporating such a system into the proton EDM storage ring and evaluates its potential to preserve beam polarization and quality, both essential for advancing EDM experiment.
