Cosmic rays
Abstract:
Cosmic rays are energetic particles originating from outer space that impinge on Earth`s atmosphere. They will hardly ever hit the ground but will collide (interact) with a nucleus of the air, usually several ten kilometers high. In such collisions, many new particles are usually created and the colliding nuclei evaporate to a large extent. The particles are tracked through the atmosphere until they undergo reactions with the air nuclei or - in the case of instable secondary - decay. This can only be achieved by detailed Monte Carlo calculations taking into account all knowledge of high energy strong and electromagnetic interactions. Therefore, a number of computer programs are used to simulate the development of EAS in the atmosphere.
Detailed simulations of such processes are time consuming, thus computer clusters like ALICEnext are a very powerful tool to obtain high statistics faster. Scientific results all together with the advantages given by the use of computer clusters, in this case ALICEnext, are presented. Part of ALICEnext is assigned to be used in the Physics Faculty, being handed over to Bucharest by the University of Wuppertal, Germany. This presentation will summarize the ALICEnext performances.
