Description
Summary:For experiments with polarized protons and deuterons, the NICA collider is planned to be used in the transparent spin mode, which is provided by two solenoid snakes. The required direction of polarization in the SPD detector is set by "spin navigators", which are insertions that rotate the spins at small angles. The polarization outside the SPD detector is determined by arc dipoles and the placement of snake solenoids in the collider. The kinematics of beam polarization is calculated when vertical, longitudinal or radial polarization is set in the SPD detector for different schemes of placement of snake solenoids. The results are relevant to solve the problems of injection and polarimetry for conducting experiments with polarized beams in the spin transparency mode.
