摘要：
Analyzing time-of-flight neutron total scattering data involves many instrument-dependent corrections, including: detector deadtime, normalization of detector counts to beam monitor counts, time-of-flight to momentum transfer Q rebinning, use of vanadium (or an equivalent standard) data for both calibration and data-merging purposes, as well as attenuation, multiple scattering, and inelastic effects. Here we review and discuss these methods in the application to data analysis of the Glass, Liquid and Amorphous Materials Diffractometer at the Intense Pulsed Neutron Source. The implementation in the Integrated Spectra Analysis Workbench (ISAW) software suite is discussed in detail. Published by Elsevier B.V.
