Description

The GRAPES-3 is an extensive air shower experiment consisting of ~400 scintillation detectors and 560 m^2 large area tracking muon detector, located at Ooty (2,200 m asl), India. The expansion of the array is in active phase to improve its performance for gamma ray astronomy, and for the study of the chemical composition of the primary cosmic rays above ~10 TeV. During this expansion, both the area of the scintillation detector array and the area of the muon detector will be doubled. In this presentation, the current status of the expansion project, and expected performance of the upgraded GRAPES-3 extensive air shower array will be reported.
