PNPI wide-aperture fan neutron supermirror analyzer of polarization

A wide-aperture fan neutron supermirror analyzer of polarization is presented in the paper. The analyzer has been made in PNPI (Gatchina, Russia) for the neutron reflectometer NeRo in GKSS (Geesthacht, Germany). The analyzer is installed in front of the two coordinate position-sensitive detector with sensitive area 250×250 mm2. The neutron wavelength is 4.35 Å. The analyzer consists of 90 channels, and its entrance cross-section is 90×160 mm2. In the paper, the results of tests of the analyzer are presented.
