Description
The methods for independent measurements of proton and antiproton beam polarizations at the SPASCHARM experiment at U-70 of IHEP, Protvino, are discussed. The fist approach exploits the single-spin polarization asymmetry AN in elastic pp-scattering in the Coulomb-Nuclear Interference and diffraction kinematic regions. The second approach is based on using the earlier observed large AN asymmetry in inclusive charged pion production. The data accumulation times and measurement accuracies are estimated for the both methods and compared.
