Abstract:
The article demonstrates the capabilities of the MNS (multifunctional neutron spectrometer) installation at the IN-06 pulsed neutron source at the IN-06 Institute of Nuclear Research of the Russian Academy of Sciences after retrofitting with a 2D NEUTRON DETECTOR for small angle neutron diffraction (SANS). Digital processing of the data array obtained from the ND using the programmes developed by us allows to obtain diffractograms and beam profiles from the data of one measurement with the possibility to vary the resolution and intensity of the diffractograms. We also demonstrate a method of data array processing that allows to get diffractograms of high resolution and intensity simultaneously, similar to the method of time focusing. The measurements were carried out on samples of heat-resistant alloy MoTiC (Mo – basic, Ti – 1%, C – 3%), on a neutron diffractometer MNS on a pulsed neutron source IN-06 INR RAS.
