Highly Superperiodic Structure of the Nuclotron with Quasi-Frozen Spin for Studying the Electric Dipole Moment of Light Nuclei

The task of adapting the Nuclotron structure to the requirements for the structure for measuring the electric dipole moment of the deuteron and proton can be determined by a set of problems of spin-orbit motion: the presence of straight sections with dispersion for placing three families of sextupoles that suppress the decoherence of the spin precession and maintain the spin direction along the ring. High superperiodicity of the developed quasi-frozen structure is necessary for the proton beam due to the high anomaly of the magnetic dipole moment of the proton. The goal of the proposed work is to determine the relationship between the Nuclotron and the NICA collider, including a modification of the Nuclotron magneto-optical structure to create a synchrotron with two functions in one accelerator: a booster of polarized proton and deuteron beams for injection into the collider and an independent synchrotron-storage ring for conducting precision experiments on the study of the EDM of light nuclei and the search for an axion.
