Spectrometer–telescope calibration by cosmic muons

Abstract

The results of cosmic-muon calibration of the multichannel lead–scintillation “sandwich”-type spectrometer–telescope intended for operation in high-intensity photon and electron beams, capable of determining the beam energy and forming intrinsic trigger, are presented. It was found that the relative energy resolution at an average energy release by cosmic muons in the spectrometer of ∼26 MeV is from 7.5% to 23% depending on the internal and external trigger version.
