      abstract     = {The 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
