摘要：
We have designed and constructed a high-performance neutron polarimeter for ((p) over right arrow (n) over right arrow) measurements at intermediate energies, E(p) = 200 - 400 MeV. The current version of the neutron polarimeter, called NPOL2, consists of 6 planes of the two-dimensional position-sensitive neutron detectors with a size of 1 mx1 mx0.1 m. Its effective left-right analyzing power < A(y)(eff) > has been calibrated at 141, 191, 291 and 387 MeV. The Figure-Of-Merit value defined by < A(y)(eff) >(2) x epsilon(DS) is about 4x10(-4), irrespective of neutron energies, where epsilon(DS) is the double scattering efficiency.
