Long-Term Analysis of the Energy Calibration of LVD Counters

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

The LVD experiment, located in a low-background Laboratory of the Gran Sasso, is designed to search for supernovae neutrinos burst and for studying cosmic ray muons. As part of the studies of variations of atmospheric muons underground, we analyzed the obtained energy calibrations of the LVD counters in the energy range of 50−450 MeV. Energy calibration of 840 LVD counters is carried out monthly through muons passing through the detector. The procedure consists in obtaining the muon spectrum average in the form using the ADC linear channels and then in the approximation of the spectrum of each counter to determine the channel number corresponding to the muon peak. We show a seasonal change in the position (channel) of the “muon peak” used for calibration.
