Spin Navigator Based on Correcting Dipoles of the JINR Nuclotron

A spin navigator based on correcting dipoles has been proposed to manipulate the directions of protons spins in experiments at the Nuclotron synchrotron (JINR, Dubna). The polarization is controlled by means of the controllable distortion of the beam closed orbit by correcting dipoles, which ensures...

Description
Summary:A spin navigator based on correcting dipoles has been proposed to manipulate the directions of protons spins in experiments at the Nuclotron synchrotron (JINR, Dubna). The polarization is controlled by means of the controllable distortion of the beam closed orbit by correcting dipoles, which ensures the significant enhancement of the action of the navigator on the spins of particles. A method has been proposed to measure the coherent effect of the lattice imperfection on the spin dynamics by the navigator. An idea of a spin compensator based on correcting dipoles is presented, which allows one to eliminate the effect of the lattice imperfection on the polarization. The proposed navigator and spin compensator make it possible to perform a series of experiments at the Nuclotron to verify a new polarization control technique called the spin transparency mode. The results are relevant for experiments with polarized beams in the spin transparency regime at the NICA (Dubna, Russia) and EIC (Brookhaven, United States) and the COSY synchrotron (Julich, Germany).
