Data analysis of the first physical run and calibration of the RED-100 detector

This poster is devoted to the data analysis of the RED-100 experiment for the coherent elastic neutrino-nucleus scattering (CEvNS) study in a reactor electron antineutrinos flux. The RED-100 detector was deployed near the reactor core of the 4th module of Kalinin NPP (Udomlya, Russia) in 2021. First science run was just completed in March 2022 and preliminary results of collected data analysis will be presented. This poster is focused on the data processing: calibration, position and energy reconstruction, background events discrimination. Also comparison of simulation and real data will be discussed.
