Abstract

The main reaction used to detect Core-collapse Supernova neutrinos in physical experiments is the inverse beta decay reaction. Positrons produced in the reaction pass through a scintillator only a few centimeters thick. For the Baksan Underground Scintillation Telescope detector, which has a modular structure, the inverse beta decay reaction appears as a single trigger of an individual counter. The problem of detecting the reaction from neutrinos in the counter is due to a large background of single events with different nature. This work discusses the methodologies for evaluating the background components currently used in processing the experimental data of the detector.
