摘要

A dedicated software package, SADAR, has been developed for the reduction of two-dimensional Small Angle Neutron Scattering (SANS) data acquired from the SN2 instrument at the National Research and Innovation Agency (BRIN), Indonesia. SADAR facilitates essential data corrections, including background and sample holder subtraction, instrument parameter determination (beam center on 2D detector, transmission factor of the sample, detector efficiency), and conversion to scattering intensity as a function of momentum transfer, I(Q). Output data are stored in ASCII format, enabling subsequent advanced analysis. Validation using an AgBeh standard demonstrated the software’s efficacy, with the identification of the characteristic lamellar structure first Bragg peak at Q = 0.1089 Å1. SADAR provides a robust and reliable tool for accurate and precise SANS data processing for SN2 instrument users. The SADAR was developed using the Python programming language to ensure compatibility with wide range of computer platforms.
