POLI is a versatile two-axis single-crystal diffractometer at the FRM II, primarily dedicated to the investigation of magnetic structures in single crystals using polarized neutrons. Neutron polarization at POLI was previously realized via a MEOP (Metastability Exchange Optical Pumping) system. Recent tests have demonstrated that in-situ SEOP (Spin-Exchange Optical Pumping) polarizers can...
The MAGiC Instrument at the European Spallation Source is a polarized neutron diffractometer dedicated to magnetism and magnetic phenomena in solid-state systems. To facilitate its science case, MAGiC will have a permanently polarized beam of cold and thermal neutrons, as well as all necessary capabilities for polarization analysis of the scattered neutrons.
The flux of the cold moderator...
The IMAGINE instrument, located within the High Flux Isotope Reactor (HFIR)’s cold guide hall at the Oak Ridge National Laboratory (ORNL), is receiving a major upgrade to enable the use of Dynamic Nuclear Polarization (DNP). The IMAGINE instrument is a Quasi Laue neutron diffractometer used primarily for the study of protein crystallography. Within the field of protein crystallography,...
GP-SANS at HFIR is one of the highest flux small angle neutron scattering instruments in the world with high user demand. The user community has expressed interest in GP-SANS obtaining full beam polarization to help build out the range of experiments that could be performed. In 2020, the GP-SANS team developed a polarization concept for a v-cavity, magnetic housing for the v-cavity, magnetic...
Oak Ridge National Laboratory (ORNL) has built and commissioned a development focused thermal beamline at the HB-2D position of the High Flux Isotope Reactor (HFIR) with the goal of testing neutron scattering instrumentation and advancing neutron scattering methods, and a special focus on polarized neutron techniques. POPLAR was designed to be as flexible and configurable as possible and can...
