Intermediate-energy polarimeter for the measurement of the deuteron and proton beam polarization at the JINR synchrophasotron

The vector polarization of the deuteron beam of the JINR Synchrophasotron (2.5⩽Pd⩽9.0 GeV/c) was measured and monitored by the pp beam polarimeter. Considering the deuteron beam as a beam of weakly bound protons and neutrons, the asymmetries of scattering of protons from deuterons on thin polyethylene and carbon targets were determined. The polarimeter is described, and the values of the vector polarization of the deuteron beam and of the CH2 analyzing power are given.
