The new ATSAS release includes installers for current major platforms (Windows, Linux and Mac OSX) and provides improved indexed user documentation. They include (i) multiplatform data manipulation and display tools, (ii) programs for automated data processing and calculation of overall parameters, (iii) improved usage of high- and low-resolution models from other structural methods, (iv) new algorithms to build three-dimensional models from weakly interacting oligomeric systems and complexes, and (v) enhanced tools to analyse data from mixtures and flexible systems. Our approach relies on certain stability estimates for the Gaussian log-Sobolev and Talagrand transportation inequalities.New developments in the program package ATSAS (version 2.4) for the processing and analysis of isotropic small-angle X-ray and neutron scattering data are described. Let $\gamma$ be the standard Gaussian measure on $\mathbb(\mu) $ is bounded from below under the assumption that the Gaussian Fisher information of $\nu$ is finite and prove a priori estimates for the minimizers. It concludes that the key parameters of small angle neutron scattering spectrometer can be achieved by using silver behenate, which supports the exact analysis and inversion for experiment data of small angle neutron scattering. The wavelength resolution of the velocity selector is 23.75% by fitting these experiment data and the spectrometer Q resolution curves can be obtained by using the chosen layout parameter and different rotating speeds. nm, correspondingly, four different selecting neutron wavelengths are 0.776, 0.582, 0.466, 0.388 nm, respectively.Obtained results show that the velocity selector constant is 2329.2 r Finally, these experiment data were inversed and analyzed. Then, the spectra of small angle neutron scattering on silver behenate were obtained under four different revolving speeds of mechanical velocity selector. First, the geometrical layout of spectrometer was chosen including the size of circular source, sample apertures of the collimator, the source-to-sample distance and the sample-to-detector distance. To calibrate quickly key parameters of a small angle neutron scattering spectrometer, such as selecting neutron wavelengths, wavelength resolution, and the Q resolution under a geometrical layout of the spectrometer, the experiment data of small angle neutron scattering for silver behenate powder were fitted.
