Description

The GRAPES-3 experiment is a unique facility to study cosmic ray energy spectrum and composition with high precision. It consists an array of 400 plastic scinitillation detectors and a muon telescope of 3712 proportional counters to study extensive air shower (EAS) phenomenon around knee ($geq$10$^{15}$ eV). Study of energy spectrum and composition of primary cosmic rays (PCRs) can improve the understanding about the nature of the sources accelerating PCRs to energies (geq 10^{15}) eV which may be studied by using high statistics data produced by GRAPES-3. Measurement of particle densities ($geq$5000 m$^{-2}$) is achieved by viewing each scintillator with two photomultiplier tubes (PMTs). The results obtained till date will be presented at the conference.
