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 ...

Polarimetric NSE demonstrated On a standard spin-echo spectrometer, the fact that the beam is essentially depolarised right before the sample is unimportant in systems where there is no sp ... functions which are useful for carrying out neutron scattering experiments, especially with polarised beams. This plug-in is free and may even ...

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 ...
