CAEN S.p.A., an important industrial spin-off of the INFN (National Institute for Nuclear Physics), is pleased to present its new activities in the educational field. CAEN brings the experience acquired in almost 40 years of collaboration with the High Energy & Nuclear Physics community into the university educational laboratories by providing modern physics experiments based on the latest technologies and instrumentation. CAEN has realized different modular Educational Kits, all based on Silicon Photomultipliers (SiPM) state of-the-art light sensors with single photon sensitivity and unprecedented photon number resolving capability. They have proven to be suitable for an increasing number of applications in science and industry. The main goal is to inspire students and guide them towards the analysis and comprehension of different physics phenomena with a series of experiments based on state-of-the art technologies, instruments and methods.
The existence of cosmic rays was discovered by Victor Hess in 1912, performing experiments on the ionization of the air. The cosmic radiation is composed by ener-getic particles mainly originating outside the Solar System and even from distant galaxies. It could be divided into two component: “primary” and “secondary”. Of primary cosmic rays, which originate outside of Earth’s atmosphere, about 99% are the nuclei of well-known atoms and about 1% are solitary electrons. Of the nuclei, about 90% are protons, 9% are alpha particles and 1% are the nuclei of heavier elements. A very small fraction are stable particles of antimatter, such as positrons or antiprotons. When cosmic rays penetrate the Earth’s atmosphere they collide with atoms and molecules, mainly oxygen and nitrogen. The interaction produces a cascade of lighter particles, a so-called shower secondary radiation, including protons, x-rays, muons, alpha particles, pions, electrons, and neutrons (figure 1). In first approximation about of 30% of the secondary radiation is composed by electrons and photons, while the 70% by muons.
In questa tesina ho scelto di parlare dei raggi cosmici e dell’esperimento di Rossi e Hall, che ha ispirato la realizzazione del piccolo esperimento presentato nella seconda parte. Parlerò infine delle applicazioni pratiche della misura del flusso di muoni cosmici
Quel est le taux de rayons cosmiques en fonction de l’altitude et de la profondeur géologique? Théorie et mesures. La physique et l’astronomie en particulier sont des sciences qui me passionnent depuis quelques années et je compte poursuivre mes études dans ce domaine. Le travail de maturité est une occasion d’approfondir un sujet qui me captive vraiment et qui peut m’être utile dans le futur. Lorsqu’on nous a présenté les différentes formes de travail de maturité, je me suis interrogé sur la façon dont je souhaitais conduire mon projet: effectuer un travail de recherche en répondant à une problématique mais également mener un travail d’expérimentation me semblait intéressant. J’ai eu par conséquent l’idée de combiner la pratique et la théorie, en réalisant des mesures tout en répondant à une problématique.
