A polarized neutron spectrometer intended for studies of interactions of nu
clei and condensed matter with polarized neutrons with energies in the rang
e from thermal energies to several electron volts was designed at the IBR-2
pulsed reactor (JINR, Dubna). Diffraction on magnetized Co(92%)-Fe(8%) sin
gle crystals was used to polarize neutrons and analyze the polarization. Th
e attained neutron polarization was similar to 95% within the entire energy
range.
