Abstract:
'A large area (560 m$^2$) muon telescope in the GRAPES-3 experiment at Ooty, India records muon intensity at high cutoff rigidities (15–24 GV) along 169 independent directions spanning a field of view of 2.3 sr. The threshold energy of the recorded muons is sec(θ) GeV along a direction with a zenith angle (θ) and with the average angular accuracy of ~4°. The directional capabilities of the muon telescope are exploited for studying the effect of atmospheric pressure on the muon flux as a function of θ. The analysis details and results will be presented.'
