Polarised neutrons have long been used to study magnetic structures and dynamics in nano- to meso-scales [1]. In soft matter studies, polarisation analysis has recently been shown to be an important method to determine coherent and single-particle motions in QENS in the intermedia length scale where diffusion occurs [2,3]. Owing to the persistent push to advance the technology, polarised...
The latest instrument specifications of the J-PARC MLF BL02 spectrometer are introduced, and the future of scientific research expected from the use of polarized neutrons will be summarized from the viewpoint of the instrument scientist in charge of the spectrometer.
Neutron polarization analysis provides profound additions of knowledge to the field of soft condensed matter research. The ability to separate the coherent and incoherent scattering contributions gives information on spatial correlations and collective motion, and information from single particles, respectively.
In this study, we focus on upgrading the SPHERES (SPectrometer for High Energy...
T-REX is a bi-spectral direct geometry neutron chopper spectrometer, currently being constructed at the ESS. The instrument is a collaboration between Forschungszentrum Jülich and Consiglio Nazionale delle Ricerche (CNR). It is a very versatile instrument and will mainly focus on probing single crystals in the scientific areas of low dimensional, topological and frustrated materials, quantum...
SHERPA is a proposed near-backscattering instrument that will replace the IRIS spectrometer on the first target station at ISIS. By exploiting the prismatic effect of the PG(002) crystals in the secondary spectrometer, it promises huge gains in count-rate versus current ISIS instruments. This will facilitate routine polarization analysis on both small samples and weakly scattering materials....
MDANSE (Molecular Dynamics Analysis of Neutron Scattering Experiments) [1,2,3] is an open-source software project developed to allow users to generate simulated neutron scattering observables from MD trajectories relevant to inelastic and quasi-elastic neutron scattering experiments. The MDANSE project began in 2015, supported by the SINE2020 program, and was initially developed by software...
In neutron polarization analysis studies changes of neutron beam polarization are observed, which are exclusively due to the interaction of the neutron spin with a sample studied. The interactions can be of two types: with nuclear spins and with magnetic fields inside the sample i.e. primarily between the nuclei. In NSE spectroscopy the behavior of the neutron beam polarization along neutron...
