Система сцинтилляционных годоскопов эксперимента NA62

The system of scintillation hodoscopes for the "Kaon Factory" (NA62) experiment at CERN was developed, created and successfully operating with the active participation of the group from NRC "Kurchatov Institute" - IHEP (Protvino). The system consists of four independent sub-detectors, which are located in different zones in the experimental hall and are designed using different technologies: with scintillation tiles read by wave-shifting fibers, as well as using a short light guide or an air gap with dimming. SiPMs or PMTs are used as photodetectors. Each detector is designed for a specific functionality and specific requirements. \par The NA62 experiment is designed to operate with a high intensity (750~MHz) slow-extracted beam from SPS. Therefore, the main requirement for all the sub-detectors of the NA62 apparatus is a good time resolution. This thesis work describes in detail the different stages of R&D, simulation and tests of the individual counters for CHOD and ANTI-0 hodoscopes. With description of the experimental setups and methods to study the characteristics of counters. The studies were carried out both with the use of cosmic rays and using the extracted beams of charged particles from the following accelerators: U70~ (Protvino), PS and SPS(CERN) and DESY(Hamburg). The results of efficiency studies of the CHOD prototype in the pilot run in 2015, and then of the full-sized detector in the run1~(2016-2018) obtained using the reconstructed $K^+\to \mu^+\nu_{\mu}$ decays.
