抄録

We have designed and constructed a high-performance neutron polarimeter for (p→, n→) 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 m×1 m×0.1 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∈ds is about 4×10^-4, irrespective of neutron energies, where ∈ds is the double scattering efficiency.
