000906172 520__ $$aThe  proposed  method  exploits  charged  particles  confined  as  a  storage  ringbeam (proton, deuteron, possibly3He) to search for an intrinsic electric dipolemoment  (EDM)  aligned  along  the  particle  spin  axis.  Statistical  sensitivitiescould approach 10−29ecm. The challenge will be to reduce systematic errorsto similar levels. The ring will be adjusted to preserve the spin polarization, ini-tially parallel to the particle velocity, for times in excess of 15 min. Large radialelectric fields, acting through the EDM, will rotate the polarization from thelongitudinal to the vertical direction. The slow increase in the vertical polar-ization component, detected through scattering from a target, signals the EDM.The project strategy is outlined. A stepwise plan is foreseen, starting with on-going COSY activities that demonstrate technical feasibility. Achievements todate include reduced polarization measurement errors, long horizontal planepolarization lifetimes, and control of the polarization direction through feed-back  from  scattering  measurements.  The  project  continues  with  a  proof-of-capability  measurement  (precursor  experiment;  first  direct  deuteron  EDMmeasurement),  an  intermediate  prototype  ring  (proof-of-principle;  demon-strator for key technologies), and finally a high-precision electric-field storagering.
