Abstract: New actively shielded asymmetric vertical field split-coil superconducting magnet with maximal field of 8 T has been recently procured and implemented on the beam line POLI at Maier-Leibnitz Zentrum (MLZ). The magnet is designed in order to facilitate the single crystal diffraction with polarised neutrons. In order to provide high neutron polarisation in the vicinity of the new strong magnet a dedicated compact-size solid-state supermirror bender polariser optimised for the short neutron wavelength on POLI has been built. A Mezei flipper, which had been previously developed for lower field, could be upgraded with additional guide fields in order to be used in combination with new polarizer and magnet. All components are discussed and the performance test for the entire setup is presented. High efficiency of the new polarised neutron diffraction setup on POLI is demonstrated. Polarized neutron diffraction experiments in the fields up to 8 T are now available at MLZ.
