momentum resolution δ|Q| is about δ|Q| ≈ 0.02 Å-1. If needed, δ|Q| can be considerably enhanced by beam collimation with compromises in neutron flux. Sample environment ThALES is compatible with most of

the beam can be polarised simultaneously (i.e. select only the neutrons which have spins all in the same direction). The monochromatic beam is shaped by a set of slits and can be shut-off by a beam shutter ... n direction at will. The monochromatic polarised beam is then reflected by the sample. A second flipper and an analyser measure the change ...
