Deuteron beam vector polarisation measurement using proton-proton quasielastic scattering

Publications, 12 March 2024

The journal Nuclear Physics published an article by a group of authors (Ivan Volkov et al.) from the Joint Institute for Nuclear Research, the University of Žilina (Slovakia), the National Institute for Research and Development in Electrical Engineering (Romania) and Belgorod State National Research University (Russia) on the measurements of the vector polarization of a deuteron beam using quasi-elastic proton-proton scattering at energies of 500 and 650 MeV/nucleon.

During the work at the Nuclotron internal target station, the vector polarization of a deuteron beam was obtained with the use of data from proton-proton quasi-elastic scattering on a polyethylene target. Useful events were selected using the time and amplitude information obtained with the help of scintillation detectors. In order to obtain asymmetry on hydrogen, the carbon background was subtracted. The vector polarization values were obtained at beam energies of 500 and 650 MeV/nucleon. The obtained values were compared with the polarization values obtained in deuteron-proton elastic scattering at an energy of 135 MeV/nucleon.
