Recent results from the GRAPES-3 experiment

Abstract

The GRAPES-3 experiment located in Ooty, India at an altitude of 2200 m is operating with a dense array of scintillator detectors and a large area muon telescope to sample the electromagnetic and muonic components in the cosmic ray showers respectively. It records about a billion shower events per year. Here we discuss the GRAPES-3’ s recent measurements of cosmic ray proton energy spectrum below the Knee. We provide an overview of the cosmic ray small anisotropy results at TeV energies with two distinct structures which are also consistent with the observation of other air shower arrays. The status of the upgrade of the GRAPES-3 experiment is discussed
