Polarimetry in the Accelerator Complex of the NICA Collider

Experiments with accelerated beams of polarized protons and deuterons (possibly beams of 3He++ nuclei) are planned in the NICA collider. This paper presents the developments of polarimeters for the entire range of beam energies from the source to the maximum beam energy in the Nuclotron and the collider. The implementation of the polarimeter system will allow adjustment, optimization and monitoring of polarized beams parameters out of the source, during the transportation and acceleration processes and measuring the polarization of proton and deuteron beams in the Nuclotron and the collider with the required for experiments absolute accuracy.
