This paper summarizes the efforts to design a prototype EDM (Electric Dipole Moment) storagering in the frame of the CPEDM collaboration, with predominantly electric bending. Operated atproton beam energies between 30 and 50MeV, the main purpose of this ring will be to carry outR&D work related to a final 233MeV frozen-spin proton EDM ring. After demonstrating satisfactorybeam lifetime and spin coherence time in the electrostatic ring, clockwise and counterclockwisebeam operation, beam spin control, beam-based element alignment, and methods forreducing systematic errors in EDM measurements will be investigated. At these reduced protonbeam energies, the (weak) superimposed magnetic field required to freeze the proton spins canbe provided by powering the iron-free (hysteresis-free) "cosine-theta" coils built into the ring design.This will allow the development of EDM measurement techniques and permit the first directprecision measurement of the proton EDM. |
