  1. hisparc project: outreach hisparc mission examples of students participation progress 2004 plans for 2005 Hisparc Status

  2. Showers • Hisparc: outreach project • bring high-school students in contact with science • participate in scientific experiment • air showers: highest energies occur rarely (e.g. 1 event per 100 square kilometer per year) • determine energy and direction with scintillators on school roofs. (figure from Nagano en Watson, Rev. Mod. Phys. 72, 689 (2000)).

  3. detector • 2 scintillator detectors placed a few meters apart (typical coincidence rate of 0.3 Hz) • a GPS antenna for accurate timing • From the ‘profielwerkstuk’ from Utrecht (Pieter de Goeje, Veerle Bodewes, Brend Wanders) http://osg-schoonoord.doorn.kennisnet.nl/vwo-5/intern/napohisparc/

  4. Activities 2004 • Nahsa (Nijmegen, Charles Timmermans) started in 2002. • increased to 7 active detectors • focuses also on data analysis • published first scientific result (NtvN). • Active detectors in Amsterdam (14 built, 12 installed) • new electronics • hisparc website, www.hisparc.nl (Kees Huyser) • Leiden • 1 detector active, above minigrail • 2 more in progress in region Leiden. Next year: Khartoum Sudan (pierre van Baal) • Utrecht • 1 detector active, 2 being built • measured tracks • Groningen • 4 detectors being built

  5. High school student activities • In Nijmegen: building and analysis • In other clusters: mainly building the detector

  6. Student activities • about 150 “profielwerkstukken” • building detector • particles, muons, cosmic rays, showers, scintillation, photo-electric effect • oscilloscope, impedance matching, fast electronics • hardware, grinding, polishing etc. • calibrations, excel, statistics (Poisson, Gaussian distributions) • several movies and interviews • most schools with web sites • software development • cosmic rays • GPS positioning • weather • promotion videos etc. students calibrating a scintillator plate

  7. Hisparc DAQ

  8. Data retrieval • Data : retrievable via website • mysql database

  9. data analysis • Rate dependence on weather ( F. Hidde, Herman Wesselink College) • thunderstorm on Nov. 26

  10. Electronics • lineair amplification • modified filter, impedance matching, integrator circuit • 12 volt circuit for photomultiplier tube • modified coincidence timing • integrated scalers • many thanks to Henk Peek

  11. Electronics, Altran • current design not scalable, too much man power involved • Improved design from Altran • Rob Derlage (Altran) • analog part: Hans Verkooijen (NIKHEF) • usb interface • integrated ADC’s – 440 MHz sampling • integrated GPS timing • fully programmable logic and settings • up to 4 channels • scaler readout, etc. • cost reduction, factor 3

  12. Altran design (Rob Derlage) technical design specifications are being discussed now

  13. Press Coverage • many (~50) news paper articles • including 3 in Volkskrant and 1 in NRC • Natuur, wetenschap and techniek • intermediair • national radio, television Noord Holland • article in Nature • june 17, 2004 vol. 6993 • first scientific results in Nederlands tijdschrift voor Natuurkunde (Charles Timmermans)

  14. Outlook • Next year: get most out of Altran award • ready to grow • electronics • data warehousing • funding, professional organization • electronic learning environment (J. Colle and F. Hidde) • analysis, profielwerkstukken, teacher network (F. van Liempt et al.) • contacts with Coach people (Amstel Institute) • hisparc analysis in coach, detector compatible with coach • European contacts (Poland, Sweden, Portugal, England...) • make detector network • www.geluids.net • weather information • Lofar – Nijmegen is testing with a Lofar detector • possible grid at high schools, virtual school lab • Peter Sloot (UvA)

  15. Virtual laboratory Sound LOFAR Wind Cosmics … … … GPS Intelligent Detector Interface Grid Middleware …High School Network… Connect experiments, data and students in ‘Virtual Laboratory’
