Analyzing sub-100 GeV showers with the MAGIC Telescope — •David Paneque — Max-Planck-Institut für Physik, Föhringer Ring 6, 80805 München

The MAGIC Telescope is an Imaging Air Cherenkov Telescope located on the Canary island of La Palma, at the Roque de los Muchachos Observatory. The main goal of the experiment is to cover with high sensitivity the energy region between 30 GeV and 300 GeV in gamma-ray astronomy, which is inaccessible up to now. Observations in this new window of the electromagnetic spectrum are expected to provide key data for the understanding of a wide variety of astrophysical phenomena belonging to the so-called non-thermal Universe.

The analysis of sub-100 GeV showers requires an accurate calibration of the telescope, as well as a noise level significantly below the faint signals recorded in the telescope camera. But this is certainly not sufficient. The reconstruction of these low energy events is quite complex due to the fact that the images on the telescope camera are produced by fewer and more dispersed particles than the showers at higher energies. In addition, the Earth magnetic field distorts these images in a way that depends on the incident direction of the showers. Because of that, the conventional analysis techniques might not be able to reconstruct efficiently sub-100 GeV events. In the presentation I will report on activities which are going on within the MAGIC collaboration to target the challenging analysis of sub-100 GeV showers.
