Magneto-Optical Structure of the Nuclotron for Searching for the Electric Dipole Moment of Light Nuclei

A possible magneto-optical structure of the Nuclotron is considered, which could provide the conditions for an experiment to measure the electric dipole moment of the deuteron. To this end, it was necessary to solve four problems for eight superperiodic structures: implement the concept of “quasi-frozen spin” in the proposed optics, increase the lengths of the straight sections between arcs, ensure zero dispersion in the straight sections, and, as far as it is possible, preserve the length of the accelerator ring, taking into account accommodation of the required equipment. In addition, the transition to a magneto-optical structure with superperiodicity N = 16 is considered, which will bring the properties of the “quasi-frozen” structure closer to those of the “frozen” structure by reducing the beam rotation angle on each arc. At such angles for deuterons, the feasibility of searching for the electric dipole moment of the proton is also considered.
