Science in the Schools: The Extreme Energy Events project

The Extreme Energy Events (EEE) project, a cosmic ray physics experiment, is at the sametime an excellent outreach project. Its scientific goal is the study of extended air showers from high energy cosmic rays and extreme energy events by detecting the muon component of the shower. To this aim, a network of muon telescopes has been installed in high schools distributed all over Italy; each telescope consists of three planes of Multigap Resistive Plate Chambers which allow the reconstruction of the muon direction. The search for extended air showers is based on the search for coincidences between telescopes. The project was conceived by Prof. A. Zichichi in order to interest high school students in science and give them a hands-on experience of scientific researc

First detection of Extensive Air Showers with the EEE experiment

The Extreme Energy Events (EEE) project is devoted to search extremely high energy cosmic rays, by means of an array of hodoscopes distributed over the Italian territory. These stations are based on the use of Multigap Resistive Plate Chambers (MRPC), that have excellent time resolution and good tracking capability. They are installed in selected secondary school institutes, where students are involved in the research work. In this article the analysis of the first extensive air shower detected is presented

Towards the installation and use of an extended array for cosmic ray detection: The EEE Project

The Extreme Energy Events (EEE) project started to use an array of cosmic ray telescopes for muon detection, distributed over the italian territory. The use of such telescopes, based on Multigap Resistive Plate Chambers (MRPC) allows the study of the local muon flux, the detection of cosmic ray showers and the search for correlations between distant showers. The project is also intended to involve high school teams in an advanced research work. The present status of the installation and the first physics results are discussed here

The Extreme Energy Events experiment: cosmics rays multigap resistive plate chambers and high school students

The Extreme Energy Events project has been conceived to join the scientific interest of a real cosmic rays physics experiment with the enormous didactic potentiality deriving from letting it be carried out by high school students and teachers. After the initial phase, the experiment is starting to take data continuously, and the first interesting physics results have been obtained, demonstrating the validity of the idea of running a real physics investigation in these peculiar conditions. In this paper an overview of its structure and status is presented; also few results obtained at the sites are included

Proposal for an MRPC system with high-precision timing in the LVD structure

The purpose of this paper is to present a project in order to verify -without the need of knowing the distance CERN-Gran Sasso- the discovery made by the OPERA Collaboration concerning the speed of the CERN neutrinos. The project consists of two parts. A simple one and a less simple one. Both have the great advantage of being totally independent of the knowledge of the distance, ≃ 732 km, between the two Labs, CERN and LNGS, where the neutrinos are produced and detected, respectively. The "simple" version of this project is based on the high-energy horizontal cosmic muons, which traverse LVD and OPERA detectors, thus allowing to cross-calibrate the timing systems of both experiments in a way which is totally independent of the TOF measurements of CNGS. This component of the project is being studied in collaboration with the OPERA group, as the time stabilities of both experiments are needed. In fact it is since a long time that the two groups are engaged with this problem. In this paper we will present and discuss the "less simple" part which allows to establish, at the highest possible level of accuracy, if (v > c) effects really exist
