Simulated experiment A typical neutron powder diffraction experiment with D2B: The polychromatic beam from the thermal beam H11 is collimated and is diffracted by the Ge monochromator at a large take-off ... take-off angle to obtain high resolution. The sample - usually a cylinder of powder - diffracts the monochromatic incident beam. The sample is ...

From neutron source to detector in a high-field configuration Neutrons from the reactor are moderated in the graphite hot source so that the maximum flux is at a short wavelength. Hot neutrons enter beam ... beam tube H4 and go to the polarising monochromator which diffracts only neutrons with a given wavelength and spin polarisation. The ...
