SuperSUN is an ultracold neutron source situated at the end of the H523 beamline. This line delivers a beam of cold neutrons (including 9A wavelength neutrons), which are converted into ultacold neutrons (UCNs)

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 ...

Coulter and collaborators [1] first showed that it was possible to polarise a polychromatic neutron beam by simple transmission/absorption through a polarised helium-3 filter. At the same time, Francis Tasset

is equiped with a 10 Tesla cryomagnet with a wide opening angle and a lifting detector. The neutron beam is polarised vertically. Large portions of the reciprocal space can be explored due to the relatively

temperatures (up to 3000 K). We have started building a prototype compatible with the use of polarised beams which can be installed in a few hours like a cryomagnet. It is also designed to be used in conjonction

field contour. This distance can be determined from the system stray field plot. Items such as steel beams or pillars and concrete reinforcing can cause problems, in particular any non-symmetric steel in the ... magnetised and cause areas of increased field at some distance from the system, in particular steel beams may cause increased field areas ...
