Spherical neutron polarimetry with MuPAD

Over the last decade, the systematic application of spherical neutron polarmetry (SNP) has been successfully used to investigate scientific questions which were intractable before, e.g. study of magneto-electric crystals such as LiCoPO 4 and MnGeO 3 . Until now, the only device capable of performing...

Description
Summary:Over the last decade, the systematic application of spherical neutron polarmetry (SNP) has been successfully used to investigate scientific questions which were intractable before, e.g. study of magneto-electric crystals such as LiCoPO 4 and MnGeO 3 . Until now, the only device capable of performing routine SNP measurements at finite scattering angles was CryoPAD (cryogenic polarization analysis device), presented by Tasset et al. in 1989. Recently we demonstrated that an alternative setup named MuPAD (Mu-metal polarization analysis device) based on a zero-field environment produced by highly permeable mu-metal is also feasible. Here we present this new SNP device together with some first results.
