A cosmic ray telescope has been designed to analyze the angular distribution of cosmic ray muons. The cosmic ray telescope configuration involves four scintillators, grouped in pairs with each pair separated by a distance. The size of each scintillator detector is 6 cm \(\times \) 4 cm \(\times \) 1 cm and the distance between each pair can vary from 10 cm to 50 cm. Scintillator detectors coupled with SiPMs as the primary device for detecting muons. The variation of muon flux with the zenith angle of cosmic rays follows the function form, \(f(\theta ) \propto \cos ^n\theta \) , where n depends on the latitude and longitude. The measurements at 8 different zenith angles give the value of the exponent, \(n = 2.07\) .

摘要

A cosmic ray telescope has been designed to analyze the angular distribution of cosmic ray muons. The cosmic ray telescope configuration involves four scintillators, grouped in pairs with each pair separated by a distance. The size of each scintillator detector is 6 cm \(\times \) 4 cm \(\times \) 1 cm and the distance between each pair can vary from 10 cm to 50 cm. Scintillator detectors coupled with SiPMs as the primary device for detecting muons. The variation of muon flux with the zenith angle of cosmic rays follows the function form, \(f(\theta ) \propto \cos ^n\theta \) , where n depends on the latitude and longitude. The measurements at 8 different zenith angles give the value of the exponent, \(n = 2.07\) .
