Abstract: High intensity, polarized protons can be stored in an all-electric ring to probe the proton electric dipole moment. The expected sensitivity level is 10**-29 e * cm, better than any planned hadronic EDM experiment by one to two orders of magnitude. The protons at their magic momentum of 0.7 GeV/c keep their spin vectors aligned with their momentum vectors in any transverse electric field for the duration of the storage time. However, not all protons within the acceptance of the ring, are exactly at the magic momentum. An RF-cavity is used to eliminate the first order effects responsible for the spread of angles between the spin and momentum vectors. We have used particle simulations and fourth-order Runge-Kutta integration to determine the second order effects. The spin coherence time, a measure of the angle spreads, are found to be adequate for a total storage time of 10**3 s. Further improvements, using sextupole magnets and/or stochastic cooling, could bring another order of magnitude improvement in the statistical sensitivity.
