000859473 520__ $$aThe scattered intensity in polarized neutron diffraction depends strongly on the beam polarization and the analyzing efficiency. In order to obtain accurate values, especially for magnetic contributions, a precise knowledge of the polarization parameters as well as correction for the finite polarization/analyzing efficiency are required. A new software tool, called “SNP FileScanner”, has been developed to simplify the data treatment for polarized neutron diffraction measurements performed using MEOP spin filter cells (SFC) on POLI [1]. The software tool performs three tasks:The first one is to organize the ³He SFCs used during the experiment. It allows to automatically extract the typical SFC parameters (Relaxation time and ³He start polarization with error bars) by fitting the observed experimental transmission data. It detects automatically changes in the monochromator settings, which can influence the measured transmission for the SFCs, and takes them into account.The second task is to correct spherical neutron polarimetry (SNP) data. It can automatically read out background-peak-background scan files from NICOS for the individual SNP channels and correct the observed peak intensity for the finite polarization provided by the SFC specified in the first part. It calculates and displays the components of the nuclear and magnetic structure factors (NN*, MyMy*, MzMz*, Re[NMy*], …) and the corrected polarization matrix with error bars.  Since these structure factors are determined by a least square fit to the data, corresponding R values and a plot of the measured and calculated intensities is shown.As third task, the software can correct flipping ratios and asymmetry values from spin flip measurements according to the SFC parameters provided by the first part. The software package itself is written in Qt (C++) and uses only QCustomPlot as third party library. It can be easily extended to process measurement data from other instruments.[1] V. Hutanu, M.
