A unique polarized deuteron beam with momentum up to 13 GeV/c is available at the Nuclotron complex in Dubna, Russia. A new polarized
source and a renewed pre-injector of the Nuclotron accelerator, have been built and put into operation, as part of the future NICA collider.
The deuteron beam has been used to produce polarized proton and neutron beams with the aim to measure analyzing powers on C, CH and CH2 targets. The experiment with the proton beam requires the detection of ‘one charged particle + X’ in the final state and it is based on the measurement of the azimuthal distribution of a final charged particle. In order to increase the figure of merit at the highest momenta achieved here, it has been suggested to add a hadron calorimeter, selecting one track events. With neutron beams, it is suggested that charge exchange reactions become more convenient than elastic scattering. The efficiency, the analyzing powers and the figure of merit have been measured in the relevant momentum range.
The collected data are important to optimize hadron polarimetry and are necessary for the electromagnetic form factor program at JLab, that is based on the Akhiezer-Rekalo polarization method.
