  1. High School Cosmic Ray Projects • in Europe • Gregory Snow / University of Nebraska • To replace • Dr. Bob Van Eijk / NIKHEF, Amsterdam • HiSPARC in the Netherlands • Report on 2nd CRSP meeting • (Cosmic Ray School Projects) • Lisbon, Portugal, September 9, 2006

  2. European High School Cosmic Ray Sites • Reporting at the • Lisbon meeting: • Portugal • The Netherlands • Belgium • Greece • Italy • Denmark • Poland • Russia • Sweden

  3. Group photo from first CRSP meeting NIKHEF, Amsterdam, 7-8 March 2005

  4. One slide summary of the situation in Europe • There are a few mature and several emerging like-minded efforts • Teams of high school teachers and students work with university • physics groups to study extensive air showers using school-based • detectors • Projects embrace both educational and scientific goals • All projects employ plastic scintillators placed on high school • rooftops, except EEE in Italy which will employ Multi-Gap • Resistive Plate Chambers • GPS receivers give local time stamp for cosmic ray events recorded • locally, internet allows teams to share data and search for • building-sized or city-sized showers and long-distance correlations • Most efforts are/have developed readout electronics, data • acquisition software and analysis techniques independently, relying • on local expertise • Full fledged start-up or expansion limited by funding and manpower • Desire for a more global, unified approach to eliminate duplication • of effort and to standardize/share detectors, procedures, • data format, curriculum materials, …

  5. Sites in The Netherlands www.hisparc.nl At present: 5 clusters in NL, with national project manager Groningen, Utrecht, Nijmegen, Leiden, Amsterdam (each with their own leader)

  6. Sites in The Netherlands At present: About 42 detector stations operational or pending

  7. Sites in The Netherlands Car top ski racks! GPS antennas Present price per school: 6500 Euros (20% cost is scintillator)

  8. Status HiSPARC Groningen: 4detectors Difficult to keep detectors online. Amsterdam: 20detectors Leiden: 7 detectors Utrecht: 2 detectors Nijmegen: 9 detectors

  13. The HELYCON Detector Module Greece

  14. The EEE project (Extreme Energy Events) The physics and the detector F.Riggi, for the EEE Collaboration Department of Physics and Astronomy and INFN, Catania Lisboa, September 9, 2006

  15. Pick-up electrode Mylar Carbon layer Cathode -10 kV glass (-8 kV) glass (-6 kV) glass Gas gaps ~ 300 mm (-4 kV) glass (-2 kV) glass glass Anode 0 V Carbon layer Mylar Pick-up electrode Multi-gap Resistive Plate Chambers The basic working principles Each MRPC is a stack of resistive plates, transparent to the avalanches generated inside the gas gaps. The induced signal on ext.electrodes is the sum over all the gaps Developed by the ALICE TOF group, to achieve excellent time resolution (40 ps) and efficiency

  16. Physics topics to investigate • Correlation between telescopes not too far away (i.e. in the same town) may allow the detection of extended showers initiated by high energy primaries. 1013 eV 1014 eV 1015 eV 1016 eV COSMOS Simulations of proton-induced air showers in Catania metropolitan area

  17. MC simulation (made with the COSMOS generator) of an Extensive Air Shower induced by a 1017 eV proton. At the ground level 1 million muons (red dots) arrive, over an area with radius at least 2 km. km km

  18. Toward a European Organisation Jan-Willem van Holten & Bob van Eijk Lisbon, 9 September 2006

  19. Provide platform to share experiences To optimise information exchange between the various participants: Specific scientific knowledge Instruction material for high-school teachers Instruction material for high-school students Make efficient use of limited manpower Scientific co-operation International organization: Why?
