A distributed, Grid-based analysis system for the MAGIC telescope

The observation of high-energetic γ-rays with ground based air cerenkov telescopes is one of the most exciting areas in modern astro particle physics giving insight into active galactic nuclei (AGN), pulsars, supernova remnants, unidentified EGRET sources, γ-ray bursts and cosmology. The MAGIC telescope started operation at the end of 2003. The low energy threshold for γ-rays together with different background sources leads to a considerable amount of data. The data analysis will be done in different institutes spread across Europe. The production of Monte Carlo events including the simulation of Cerenkov light in the atmosphere is very computing intensive and another challenge for a collaboration like MAGIC. The current Grid technology widely deployed over 80 sites by LCG has recently proven to be mature and well adapted to set up a distributed computational and data intensive analysis system meeting the requirements of experiments like MAGIC. The basic architecture of such a distributed, Europe wide Grid system will be presented. First implementation results will be shown. This Grid might be the starting point for a wider distributed astro particle Grid in Europe.
