Muon Background in the MAGIC-I telescope and the MAGIC-II stereoscopic system — •Emiliano Carmona and Razmik Mirzoyan — Max Planck Institute für Physik (Werner-Heisenberg Institut), München, Deutschland

The MAGIC-I telescope is currently the largest imaging air Cherenkov telescope in operation in the world. The construction of a second telescope is already finished and the two telescope system (MAGIC-II) will start the stereoscopic operation early in 2009. In this work we use Monte Carlo simulations to investigate the muon background in the MAGIC-I telescope and in the MAGIC-II stereo system. We also investigate the possibility to increase the MAGIC-II background rejection capabilities by tagging muon events. In addition, the possibility to use the MAGIC (I and II) fast signal sampling to improve the background rejection capabilities of the MAGIC system are also investigated.
