Description

Gamma ray induced air showers can be observed by particle detector arrays at high altitudes. The water-Cherekov detection technique has proven to result in robust observations of the gamma-ray sky around TeV energies and has been applied in observatories like Milagro and more recently in HAWC. The biggest challenge for these kind of observatories is to effectively reject background events from proton induced air showers. The work presented here will give a detailed overview on the differences between photon and proton induced air showers by analysing the output of air shower simulations. The air shower particle footprint is studied as a function of detector altitude and incoming direction. In addition, the particle type, number and energy distributions are studied together with the morphology particle footprint. The aim of this work is to establish the fundamental drivers for the design of a next generation wide field-of-view gamma ray observatory.
