What is the primary focus of the Gamma Ray Astronomy PeV EnergieS phase-3 project?

An important finding in the cosmic-ray proton spectrum was made by the Tata Institute of Fundamental Research's GRAPES-3 experiment, which is located in Ooty, India. It revealed a new feature at 166 TeV. GRAPES-3 is a particle accelerator designed to study the origin, acceleration, and propagation of cosmic rays, as well as the presence of the "Knee" in their energy spectrum. It is outfitted with air shower detectors and a large muon detector. It also delves into the Sun's influence on Earth, the astronomy of multi-TeV ?-rays, and the production of highest-energy cosmic rays.
