Spherical Neutron Polarimetry simulations The polarisation vector of a neutron beam can be seen as a classical vector in the space of the laboratory. In particular, the component P α in the direction α ... the polarisation matrix, we measure directly the 3 components of P c with a non-polarised incident beam. Because the magnetic interaction vector ...

helimagnets require more than the conventional neutron spin echo set-up (NSE). Indeed, the neutron beam polarisation is not necessarily flipped upon scattering. When the magnetic interaction vector is complex ... position. A solid-state polariser was added after the first Larmor precession region to repolarise the beam. This is necessary for ...

version that fits the beam profile of D20. The device is a superconducting Nb cylinder hosting a spin filter cell and in which we trap a homogeneous magnetic field. The neutron beam entering Cryopol-II is ... nitrogen monitors located before and after Cryopol-II to measure continuously the polarisation of the beam. Indeed, one can easily show that ...

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 ...

the room-temperature bore which is easy. Material in the beam The cryostat will have a very low background, since the only material in the beam (apart from the sample) will be 2 x 5 mm thick sapphire windows ... neutron access The maximum field at the sample position is to be 17 T horizontal, parallel to the beam, with 0.1% homogeneity over a 10 mm ...
