Description

A measurement of the proton EDM to better than 10-29ecm, or better, allows us to probe physics in a new regime up to ~3PeV mass scale. The use of the storage ring EDM technique permits 5 orders of magnitude improvement over current indirect measurements of dp (from Hg) and 3 orders magnitude more sensitivity on QCD inferred from neutron EDM measurements. Non-zero values of the pEDM would unambiguously point to the existence of NP. We describe the design of an electric- only ring that combines the frozen spin technique with counter-rotating proton beams that can deliver these physics objectives. The experimental and technological challenges have been addressed in detail over the last 5 years; developments in magnetic field shielding now make this a low risk and relatively low cost experiment. We present a summary of the major machine and detector components required to build this experiment.
