The Storage Ring EDM Collaboration is completing a comprehensive proposal toDOE for a sensitive proton EDM experiment at the 10-29e\cdot cm level. Thisinvolves building an electric ring of radius R~40 m, with bending provided bystainless steel plates separated by 3 cm gap, providing an electric field of 10MV/m. This ring can store protons of 0.7 GeV/c momentum, also known as "magic"due to the unique property that the spin and momentum vectors precess at thesame rate in any electric field. If the spin is kept longitudinal for most ofthe duration of the storage time, the radial E-field acts on the protonelectric dipole moment and can cause a measureable vertical spin precession.Studies on spin coherence time, on the polarimeter system, and the electricfield show that we can reach the experimental goals. A plan on the relativebeam position monitors uses currently available technology and applies it in anaccelerator environment. Some R&D is needed to establish the feasibility of theplan. Prospects of further improvement with a future upgrade for another orderof magnitude in the EDM sensitivity are also laid out.
