cradles for orienting the sample crystals, with the detector moving in a horizontal plane. Normal-beam diffractometers have a mechanism for tilting the counter out of the horizontal plane, thus enabling

kinds of scientific studies, which depends for example on the energy and flux of the incident neutron beam, polarized neutron capability and the availability of specific sample environments. IN1 TAS/LAGRANGE ... high energy resolution using the change in polarization between the incident and scattered neutron beams to measure small energy changes ...

reciprocal space, while reducing the background on the detector compared to use of the full white beam.

Instrument layout Here the instrument is shown in its classical setting for magnetic studies. The neutron beam is polarised and the sample is placed in the high magnetic field of a cryomagnet.

The instrument and its team The principle of the filling station Polarised neutron beams are essential for certain fields of research, such as the study of the magnetism of matter. Neutrons can be polarised ... the instrument can be configured into virtually any shape homogeneous polarisation over the entire beam section sufficiently wide ...
