Methodology for accounting of background in a neutron experiment with a 2D position-sensitive detector

A methodology for measuring and taking into account the background in a neutron single-crystal experiment with a position-sensitive detector is proposed. This methodology makes it possible to increase the ratio of integrated intensities to the standard deviation I/σ(I) for the diffraction reflection intensities and include in the array of experimental data the weak reflections that previously did not meet the condition I/σ(I)>3, and were not taken into account in crystallographic calculations. The methodology was tested on experimental data during structural studies of a Cs4(HSO4)3(H2PO4) crystals on the MOND diffractometer at the IR-8 reactor of the National Research Center “Kurchatov Institute”.
