Silicon Photomultipliers as Alternative System of Photomultipliers of Neutral Particle Detector in Electron-Proton Accelerators

Measurement of events that produce particles, in particular photons, is a powerful tool for the study of subatomic constituents of the universe. The purpose of this research is to consider placement in the detector, study properties and implementation of updated ZEUS detector photomultipliers for possible use in future electron-proton accelerators. The most important part of the detector ZEUS, especially when measuring neutral particles such as photons, is calorimeter ZEUS, based on the phenomena of photon emission from the excited electron, which is returned to a lower energy level.

Reconstruction of Hardronic Jets with Clustering Algorithms and Modern Statistical Methods of Data Analysis in High Energy Physics

In a wide range of statistical data processing in high energy physics jet clustering algorithms and applications for function minimization are used. The aim of the study is to validate the acceptability of the programs and FastJet and MINUIT, that provide a powerful tool for finding jets from data and Monte Carlo models after the selection of events and for the subsequent approximation method of least squares.

Correlation Analysis of Characteristics Gloss and Smoothness of Paper Tape with Purpose of Their Control in Technological Process

Through experiments conducted, we study the characteristics of gloss and smoothness of paper tape to develop the method of their technological control. By utilizing the method of statistical analysis, we prove that there is nonlinear correlation dependence between them. We calculate the parameters of regression equation, which has a parabolic form. Moreover, we find that for certain angles of incidence of light ray 70–80, the parameter of correlation communication is the correlation relation signifying 0,80–0,85.

The Method of Technology Glance Control of Tape and Sheet Materials

This study demonstrates the method of technology glance control of tape and sheet materials based on the measurement of the ratio of the reflected mirror light flow from a controllable material to a total falling light flow. We show that it is necessary to carry out the glance’s measurement of various types of materials (paper, cardboard, wood-fibrous plates etc.) at the angles not less than 75. It ensures the greatest sensitivity of a method and the least influence of material chromaticity.
