Gamma Ray Source Studies Using Muon Tracking — •Paul Doll¹ and Janusz Zabierowski² — ¹Karlsruhe Institut of Technology (KIT), 76021 Karlsruhe — ²Narodowe Centrum Badan Jadrowych, 90950 Lodz, Poland

A large area (128m2) streamer tube detector, located within the KASCADE-Grande experiment has been built. We discuss the possibility of observing gamma-ray sources by means of photo-pion produced single isolated muon tracks above the background of cosmic-ray muons using a muon tracking detector (MTD). Properties of the photo-production process in the atmosphere and of the MTD which support the identification of gammas are discussed. The sensitivity of the technique of observing the Crab energy spectrum in the tens of GeV range is discussed. Gamma spectra accumulated from Crab and a Mrk 421 flux correlation with X-ray ( RXTE/PCA) are presented.

This work was supported in part by the German-Polish bilateral collaboration grant (PPP-DAAD/MNiSW) for the years 2011-2012.
