Description
The OCRA (Outreach Cosmic Ray Activities) INFN program includes public engagement events related to astroparticle physics and in particular it coordinates the twenty INFN Units that participated in the 2019 edition of the International Cosmic Day (ICD), an astroparticle physics outreach event organized by DESY. The ICD is dedicated to high school students from all over the world, who engage in measurements of the cosmic ray flux as a function of zenithal angles and discuss among themselves the results through remote conferences. Moreover, forty students who participated in the ICD will join a three-day school at the Frascati National Laboratories (LNF) of INFN in which they will launch an aerostatic balloon to measure the cosmic ray flux as a function of the atmospheric depth using a detector made by a scintillator layer and read out by SiPMs (Silicon Photomultipliers) named ArduSiPM. The students will carry out in a modern key the famous experiment by Victor Hess, which allowed the discovery of cosmic rays and earned him the Nobel Prize. The results of the measurements carried out during the school will be presented, as well as the ICD 2019 summary and some other activities coordinated by OCRA.
