520 _ _ |a POLI is a hot neutron two-axis diffractometer at the Heinz Maier-Leibnitz Zentrum (MLZ), Germany, which uses spin-polarized neutrons for magnetic studies in particular. The instrument is used, for instance, to study complex crystal and magnetic structures, to reconstruct magnetization densities in the unit cell, and to explore phase diagrams of materials via multiparameter studies. To this end, three standard measurement setups are available on POLI reaching from unpolarized neutron diffraction under extreme sample conditions, over half-polarized diffraction to zero-field spherical neutron polarimetry (SNP). Here, we will present recent developments of the instrument. In 2024, the new in-situ 3He Spin-Exchange Optical Pumping (SEOP) polarizers for POLI were finalized. With the return of neutrons at FRM II, they will provide a high level of constant neutron spin polarization during the polarized neutron diffraction experiments. To fully replace the previous Metastability Exchange Optical Pumping (MEOP) 3He polarizers, a set of two new nutators for the SNP setup are currently in the works, of which we will present the finalized layout as well as first characterization of a prototype nutator.
