This review presents the implementation and full characterization of the polarization
equipment of the time-of-flight neutron reflectometer PLATYPUS at the Australian Nuclear
Science and Technology Organisation (ANSTO). The functionality and efficiency of individual
components are evaluated and found to maintain a high neutron beam polarization with
a maximum of 99.3% through polarizing Fe/Si supermirrors. Neutron spin-flippers with
efficiencies of 99.7% give full control over the incident and scattered neutron spin
direction over the whole wavelength spectrum available in the instrument. The first
scientific experiments illustrate data correction mechanisms for finite polarizations
and reveal an extraordinarily high reproducibility for measuring magnetic thin film
samples. The setup is now fully commissioned and available for users through the neutron
beam proposal system of the Bragg Institute at ANSTO. (C) 2012 American Institute
