1 Status of the project E xtreme E nergy E vents area of Bari Prof. F. Romano - Politecnico di Bari & INFN Bari Dott. M. Abbrescia – Ricercatore Università di Bari Dott.ssa A. Regano - Centro Fermi Seconda Conferenza dei Progetti del CENTRO FERMI, Roma Aprile 2012

2 Extreme Energy Events - La scienza nelle scuole

3 Stations coordinated by Bari INFN section Trinitapoli Bari Altamura Average distance: 65 km LC "Cagnazzi" Altamura IISS “Staffa” – Trinitapoli [II fase] LS "Scacchi" Bari [II fase]

4 Construction MRPC 2006 Installing telescope: May 2008 Acquired first event: 30 May 2008 Activity  Shifts control of the students and Logbook  Remote control and monitoring  Weather station  Lessons on cosmic rays  EEE Conference on the activity: 26 May 2011 Data acquired  130 days in 2010  155 days in 2011  100 days up to April 2012 The telescope is in acquisition! Altamura

5 Construction MRPC May 2009 Installing telescope: 2011 Acquired first event: 5 November 2011 Activity  Logbook  Remote control and monitoring  Weather station  Lessons on cosmic rays  Magazine Ipogei06 The telescope is in acquisition! Trinitapoli

6 Castle structure designed by the teachers of IISS Staffa

7 The telescope is in acquisition! Construction MRPC June 2009 Installing telescope: 2011 Acquired first event: 1 March 2012 Activity  Logbook  Remote control and monitoring  Lessons on cosmic rays Bari

8 Monitor and control HV-LV system DAQ & online analysis Room control Data transfer All remotely controlled or almost!

9 Specifications of telescopes  LV system classic  trigger electronic card: model Catania-CERN  GPS electronic card: Hytec  MRPC plane distance: 60cm  Average rate: 38Hz  LV system: model Lecce  trigger electronic card: model Catania-CERN  GPS electronic card: Hytec  MRPC plane distance: 59cm  Average rate: 20Hz  LV system: model Lecce  trigger electronic card: model Bologna  GPS electronic card: missing  MRPC plane distance: 67cm  Average rate: 12Hz Bari Trinitapoli Altamura

10 Distanza Cagnazzi-Staffa: km Distanza Cagnazzi-Scacchi: km Distanza Staffa-Scacchi:70.033km

11 Flare recorded by the Solar Dynamics Observatory (SDO) on the night between 14 th and 15 th February It is a solar flare, of category X2, followed by an important Coronary Mass Emission ( CME ) This kind of flares are constantly monitored since they can have relevant consequences on Earth Valentine’s Day Solar Flare

12 Counts of cosmic rays - Altamura telescope Decrease Forbush The Valentine’s Day solar flare as observed by the EEE Altamura telescope

13 Observed in the muon channel (rather rare) First in the world to publish Data quality comparable to the one of professional observatories (as presented to ICRC 2011) First school ever to observe a Forbush decrease

14 March 2012 Sun activity Approximate Flare Maximum: UT at Flux X 1.1 Approximate Flare Maximum: UT at Flux X 5.4

15 Forbush March 2012 Second solar flare observed by the EEE Altamura telescope Preliminary !

16 Weather – Altamura March 2012

17 Program for the future Study efficiency of the detectors as a function of temperature and pressure Determining a correction coefficient

18 It is a known effect on the RPC detector... Temperature Pressure

19 In practice During the data acquisition the efficiency of the stations EEE varies Vary the frequency of counts μ The objective is to study how the efficiency varies by comparing it with a small telescope scintillators

20 Conclusions The EEE experiment in the area of Bari: 3 active telescopes EEE The Altamura telescope acquire data almost continuosly from 3 years First school to observe two Forbush decrease In the near future, with 3 telescopes, we want … … to study detector performance under varying weather conditions … look for coincidences in the middle distance … continue the observation of cosmics phenomena EEE produces physics and …

21 … the students' enthusiasm

22 Bari first event!
