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-

Guide hall n°1, cold guide H143 Data Collection Method Quasi-Laue Ni/Ti multilayer band-pass filter (δλ/λ=30%) Typical neutron λ range ~2.8 to 3.8 Å Collimation Pinholes 0.5 to 2.9 mm Flux at specimen

Zero field setup Here, D3 is equiped with CRYOPAD and a 3 He spin filter (DECPOL). This makes it possible to monitor separately the polarisations of the incident and scattered beams, in 3 dimensions.

Simulated experiment 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.

Spherical polarimetry with CRYOPAD These movies show the adventures of neutron polarization during the passage through CRYOPAD and the sample. CRYOPAD is the acronym for “CRYOgenic Polarization Analys

First test of an 3He neutron spin filter The nuclei of a helium-3 gas (3He) can be polarised. Thanks to the strong spin-dependancy of the neutron absorption a bottle filled up with that polarised gas
