you can calculate the normalization and attenuation factors from a direct beam measurement (called 'Direct beam') and reflected beam measurments (called 'D2O'), where the first angle should have some total ... clicking 'Transfer factors' button. You can do the same transfer with the direct beam numbers and the Sample theta values. Beam ...

polychromatic neutron beam (wavelength around 2.2 Å) is backscattered on the monochromator (Bragg reflexion on a crystal lattice) with a high monochromaticity (energy resolution 10 µeV). The beam is reflected so

interferometer, the incident beam is split into two separate beams (by a thin silicon perfect crystal plate). The beams travel along different regions in space and at some point the beams are brought together ... at the neutron source at the Institut Laue-Langevin (ILL) in Grenoble, where our group operates a beam line. It is important to note that ...

passing a neutron beam through a bottle filled up with this polarised gas lead to a final beam which is of one polarisation, even for a wide range of neutron wavelengths (white beam polarisation). Part-1: ... depends strongly on its ability of producing an intense and well-polarised neutron beam, and then of analyzing the diffracted beams. This is ...
