abstract = {The proposed method exploits charged particles confined as
a storage ring beam (proton, deuteron, possibly 3He) to
search for an intrinsic electric dipole moment (EDM) aligned
along the particle spin axis. Statistical sensitivities can
approach 1029 e.cm. The challenge will be to reduce
systematic errors to similar levels. The ring will be
adjusted to preserve the spin polarization, initially
parallel to the particle velocity, for times in excess of 15
minutes. Large radial electric fields, acting through the
EDM, will rotate the polarization. The slow rise in the
vertical polarization component, detected through scattering
from a target, signals the EDM. The project strategy is
outlined. It foresees a step-wise plan, starting with
ongoing COSY activities that demonstrate technical
feasibility. Achievements to date include reduced
polarization measurement errors, long horizontal-plane
polarization lifetimes, and control of the polarization
direction through feedback from the scattering measurements.
The project continues with a proof-of-capability measurement
(precursor experiment; first direct deuteron EDM
measurement), an intermediate prototype ring
(proof-of-principle; demonstrator for key technologies), and
finally the high precision electric-field storage ring.},
