Abstract
The Extreme Energy Events project (EEE) is aimed to study Extensive Air Showers (EAS) from primary cosmic rays of more than 1018 eV energy detecting the ground secondary muon component using an array of telescopes with high spatial and time resolution. The second goal of the EEE project is to involve High School teachers and students in this advanced research work and to initiate them in scientific culture: to reach both purposes the telescopes are located inside High School buildings and the detector construction, assembling and monitoring - together with data taking and analysis - are done by researchers from scientific institutions in close collaboration with them. At present there are 42 telescopes in just as many High Schools scattered all over Italy, islands included, plus two at CERN and three in INFN units. We report here some preliminary physics results from the first two common data taking periods together with the outreach impact of the project.
Highlights
The Physics and the Project There are particles in the Universe with an energy much higher than the highest energy available at the biggest accelerators: these are the Extreme Energy Cosmic Rays, whose energy (5 1019 eV, about 8 joule) is ten million times higher than the present LHC collision energy (13 1012 eV). How can they arrive at our atmosphere without losing energy because of scattering from the photons of the cosmic microwave background? What is their origin? Which are the mechanisms which give them such acceleration? The Events project (EEE) project’s goal is to contribute to answering these questions by measuring the very low flux of these particles and their origin in the Universe detecting the ground muon component of the produced Extensive Atmospheric Showers (EAS) by an array of telescopes scattered throughout Italy
An external GPS antenna provides the ”UTC” time stamp to be associated with each event, information needed to identify muon tracks detected by far-away telescopes as belonging to the same Extended Shower, that is coming from the same primary cosmic ray
All the raw data from the running telescopes are regularly sent to CNAF [5] - on a run-by-run basis - where they are ”quality monitored” and the outputs - together with the raw data - are put on a web page which researchers and students can freely access to perform their own data monitoring and analysis
