Development of methods for processing spectra of multiple small-angle neutron scattering

A method has been developed for processing spectra of multiple small-angle neutron scattering (MSANS) to obtain information about substance heterogeneities, namely, their size and concentration. A method has been proposed for constructing the dependence of the MSANS line width on the sample thickness starting from the angular neutron distribution measured for one sample. The standard method for processing this dependence has been improved for application at any scattering multiplicity and complete account for the instrumental line of the double-crystal spectrometer. The method has been tested for the MSANS spectra of the samples of the Fe-Ni ferromagnet, Al powders, and HTSC ceramics.     

A study of the Millepede alignment algorithm on the Monte Carlo model of the HERA-B outer tracker

In this paper a method of internal alignment of HERA-B OTR PC chambers is discussed. The method is based on a simultaneous fit of the track and alignment parameters, using Millepede matrix reduction and singular value decomposition. Software implementing this idea has been developed, and the method has been studied on Monte Carlo models with different levels of simulation. A generalization of this method for the case of the nonlinear track model has been proposed. The text was submitted by the authors in English.
