SSP2012 - 5th International Symposium on Symmetries in Subatomic Physics

Theoretical studies are presented how the Electric Dipole Moment (EDM) of the electron in H-like ions in electric storage rings can be sensitively determined. The investigation follows the recent proposals to measure the muon EDM [1], the nuclear EDM [2] and the electron EDM in H-like Highly Charged Ions (HCI) [3] in magnetic storage rings, as well as the proposals to measure muon, proton and deuteron EDMs in electric storage rings [4]. The basic idea in [4] was that the electric field should compensate the centrifugal force and the injected particles would move along the closed trajectory in the ring. In the applied electric field of the order 10^{5} V/cm and the velocity of the ions 0.1 c we obtain for different ions the radii of the trajectory of the order of few meters. The electron EDM in the H-like ions is strongly (up to 10^{4}) enhanced. With the proposed experiments new constraints of about 10^{-28} - 10^{-30} e cm for the electron EDM can be established what is few orders of magnitude more restrictive than the existing boundaries.
