an intercultural opportunity exchange TRINITAPOLI The cosmic rays study: an intercultural opportunity exchange “Measure what is measurable,and make measurable what is not so” (Galileo Galilei) 1oth Centro Fermi projects meeting – EEE Project 6/7/8 march 2019 - Turin Aula Magna della Cavallerizza Reale Turin University. Prof. Giacomo di Staso Maria Chiara Samarelli Silvia Di Fidio

Liceo “Staffa” TRINITAPOLI and Lyceum “Chuicov” MOSCOW friendship and cooperation agreement

Liceo “Staffa” Trinitapoli – Lyceum “Chuikov” Moscow

TRIN-01 telescope monitoring Russian teachers and students are particularly interested in the Extreme Energy Events project

Many cultural, scientific and experimental activities were carried out during their stay Lecture by prof. Marcello Abbrescia about the EEE Project Physics Department University of BARI

Lecture by prof. Marina Trimarchi about the use of the cosmic boxes and relative data analysis Liceo Staffa_Trinitapoli

Gargano (Puglia): Data taking with Cosmic Boxes at different altitudes 12/10/2018 5 cosmic boxes Altitudes : sea level + 5 m; s.l.+ 613 m; s.l.+829 m Acquisition time: 30 minutes, with readings every 10 minutes Excel data processing: cosmics rate at different altitudes: ratio between the total # events and time Error on frequency = square root(# events)/time; normalized rate at each altitude putting 1 at altitude s.l.+ 829 histograms for each cosmic box regression fit to the data rate vs. altitude

Gargano (Puglia): different altitudes data taking 12/10/2018 Sea level + 829 m Sea leves + 613 m Sea level + 5 m

Manfredonia Castle Sea level + 5 m

Monte Sant’Angelo steep road Sea level + 613 m

Monte Sant’Angelo Castle Sea level + 829 m CB2 CB4 CB3 CB1 CB5 a 829 m s.l.m. a 613 m s.l.m. a 5 m s.l.m.

Data analysis Comparison : Erice December 2017 - Gargano October 2018 Castellammare del golfo +20 m Monte Sant’Angelo +829 m Segesta +270 m Tornante salita +613 m Manfredonia +5 m Some differences: cosmic boxes number: n. 15 in Erice - n. 5 on the Gargano promontory Locations much closer to each other on the Gargano - On the Gargano promontory the taking of data was carried out at constant pressure and temperature Puglia Sicilia

Data analysis Comparison : Gargano October 2018 - Erice December 2017 The two slopes are very similar: 0,2636 Normalized frequency variation/km Erice data 0,2818 Normalized frequency variation/km Gargano data

Data analysis Comparison: normalized lines

Data taking using n. 4 cosmic boxes indoor, on the 1 st floor, and outdoor 05/11/2018 4 cosmic boxes Altitude + 6,70 m; + 7,00 m; +11,00 m Data taking duration: 60 minutes, with readings every 20 minutes Excel data processing: Histograms for each cosmic box Normalization to the frequency measured outdoor Frequency percentage variation for each cosmic box average percentage variation

Some Lyceum Chuikov students, led by their teachers, have realised an app for the EEE Project link https://silaedr.shinyapps.io/EEE_project/

Example: TRIN-01 09/2/2019 – 10/02/2019 You choose the telescope, the time span, download the data, indicate what parameter to put on the abscissa axis

An example You choose what parameter to put on the y-axis and get the plot with the chosen data

All scientific activities made during the first 10 years of partecipation to the EEE Project have been described in the book “NOI e l’UNIVERSO, dieci anni di ricerche” by professors Giacomo di Staso e Margherita Lafata. It contains an introduction by prof. Luisa Cifarelli, nice articles by prof. Antonino Zichichi, prof. Marcello Abbrescia and doctor Fabrizio Coccetti, and includes some interesting contributions by the students of Liceo Staffa

Many thanks for your attention
