Upgrade of the polarimeter at the Internal Target Station at the Nuclotron

The results of the Polarimeter upgrade at the Nuclotron internal target are presented. This Polarimeter is intended for experiments to study of the spin structure of two-nucleon and three- nucleon short-range correlations. The measurements are performed in the frame of the DSS project. The simulation of the pd-elastic and pp-elastic scattering for 500 - 1000 MeV proton energy to optimization of the experimental setup is performed.
