Energy calibration of the NaI(Tl) calorimeter of the SND detector using cosmic muons

Abstract

The general purpose spherical nonmagnetic detector (SND) is now taking data at VEPP-2M $e^{+}{e}^{-}$ collider in BINP (Novosibirsk) in the centre of mass energy range of $0.2÷1.4$ GeV. The energy calibration of the NaI(Tl) calorimeter of the SND detector with cosmic muons is described. Using this method, the energy resolution of $5.5$ for 500 MeV photons was achieved.
