Abstract

We have designed and constructed a high-performance neutron polarimeter for measurements at intermediate energies, E_p equals 200-400 MeV. The current version of the neutron polarimeter, called NPOL2, consists of 6 planes of the 2D position-sensitive neutron detectors with a size of 1 m by 1 m by 0.1 m. Its effective left-right analyzing power has been calibrated at 141, 191, 291 and 387 MeV. The figure-of- merit value defined is about 4 X 10^-4, irrespective of neutron energies.
