Cosmic Rays

Cosmic rays are energetic, subatomic particles constantly bombard the Earth's atmosphere from all directions

The cosmic radiation, discovered by Victor Hess1 in 1912, includes all stable charged particles and it is composed by two component: “primary” and “secondary” cosmic rays. Essentially, the first ones are composed by heavy nucleus, protons (~90%) and helium (~10%), but also electrons, neutrinos, photons, some light nucleus and antimatter (positron and antiprotons). These particles are accelerated by astrophysical sources and by interacting with the terrestrial atmosphere, they mainly produce the “secondary” cosmic rays: pions, kaons and electromagnetic showers. Muons and neutrinos are products of the decay chain of charged mesons, while electrons and photons originate in decays of neutral mesons.
The experiments on cosmic rays proposed in this section are performed by using the “Educational Beta KIT”. The first application is qualitative and it is based on the verification of the cosmics. The second experiment allows the measure the cosmic flux on horizontal scintillating tile. Coming soon a Cosmic telescope will be available in order to perform the third step and measure the flux azimuthal variation.

Overview

Experiments

  • SG6211 – Muons Detection
    Cosmic rays detection by using a system composed of a plastic scintillating tile directly coupled to a Silicon Photomultiplier detector.
  • SG6212 – Muons Vertical Flux on Horizontal Detector
    Measurement of the muon vertical flux on a plastic scintillating tile. Estimation of the detection efficiency of the system by comparison between the expected rate and the measured one.
