Observation of sub-PeV gamma rays from the galactic plane using the tibet air shower array with the prototype muon detector


Abstract:

We are now proposing the 10,000m2 water-Cherenkov-type muon detector (MD) array under the Tibet air shower (AS) array to find new gamma-ray sources with a wide field of view and unprecedented flux sensitivity. In the late fall of 2007, a prototype MD in area of 100m2 was constructed under the existing Tibet AS array. In this paper, we search for sub-PeV (>200TeV) diffuse/point-like gamma rays from the Galactic plane using the muon-poor air shower events observed by the Tibet AS array and the Prototype MD.
