components of the beam conditioning part are the two background choppers, the double curvature mono-chromator with four faces and the Fermi chopper. The background choppers are rapidly pulsating beam shutters which ...

experiment The polychromatic neutron beam from the hot neutron beam tube H8 is diffracted by the monochromator, where a single wavelength is selected. The diffracted beam passes through a filter to remove ... remove the harmonics and then through slits to limit its aperture. This quasi-monochromatic beam is scattered by the sample: usually a gas, a ...
