Transcript

1. A tradition of collaboration with Japan ...more than 20 years long Giovanni De Lellis Università “Federico II” and INFN Napoli 1
2. The start Collaboration initiated in the early 1990’s in the studies of neutrinos (elementary particle poorly known at that time, still not well know today). At that time, Napoli group leaded by prof. Strolin, Nagoya University group leaded by prof. Niwa The CHORUS experiment at CERN is designed for the study of neutrino “oscillations”. It starts taking data in 1994 Very active collaboration on the development of technologies • Nagoya group was world leader in the technology of nuclear emulsions • Collaboration with Japan to promote this technique also in Italy • Long stays in Japan of young researchers to learn the technology, bring to Italy the know-how for further developments 2
3. Heart of the detector: Nuclear emulsion target Target with nuclear emulsions Calorimeter Hadron spectrometer Veto plane  - h- Muon spectrometer CHORUS experiment at CERN on a muon neutrino beam CHORUS Collaboration meeting at Eihei-ji Temple in 1997 3
4. Neutrino physics from a joint Italian and Japanese idea 4
5. Target with nuclear emulsions Muon spectrometers Super-Modulo 2 Super-Modulo 1 The OPERA experiment at Gran Sasso with a muon neutrino beam produced at CERN 5
6. The OPERA experiment in the Gran Sasso underground laboratory 6
7. The first tau neutrino observed in Naples Identified by seeing its interaction with the tau lepton production (tau leaving only 10-13 sec) 7
8. OPERA Collaboration meeting in March 2010 at Nagoya University OPERA Collaboration meeting in 2012 8
9. EU: ESS (European Scanning System) Japan: SUTS (Super Ultra Track Selector) • Scanning speed/system: 75cm2/h • High speed CCD camera (3 kHz), Piezo-controlled objective lens • FPGA Hard-coded algorithms • Scanning speed/system: 20cm2/h • Customized commercial optics and mechanics • Asynchronous DAQ software Technology developments: high speed automated microscopy Both systems demonstrate: • ~0.3 m spatial resolution • ~2 mrad angular resolution • ~95% detection efficiency 9
10. Applications also to medical physics 10 Protons and carbon ions used in hadron-therapy (Bragg peak) Scarce knowledge of the way they Interact along their path C 400 MeV/u
11. Carbon exposure at HIMAC (NIRS-Chiba, Japan) 11
12. Detection of carbon interactions upstream of the Bragg peak: identification of the interaction products Identification of H and He Film con trattamento A Identification of all fragments Carbon Boron Beryllium Lithium Helium 12
13. H Li He C 400MeV/u 220MeV/u 25cm C Li+He+H example Interaction of a Carbon ion 13
14. Muons from Cosmic Rays Detector 14 As with X-rays X-rays X-ray detector Cosmic-Ray Muon Radiography of Volcanoes
15. Investigating the internal structure of volcanoes: Unzen in Japan Emulsion films exposed in a cavern of the Unzen volcano 15
16. Rock thickness at Mt. Vesuvius Telescope Spatial profile [m] 2 km rock thickness from a telescope at 750 m a.s.l.  Substantially improved sensitivity (x 102) with respect to previous radiographies (< 1 km rock)
17. Installation of the detector in Stromboli 17
18. Stromboli volcano: detector view of the zone of interest 18
19. From Research to School • Bringing the same model of International cooperation to the School 19
20. The project: “Scienza e Scuola” http://scienzaescuola.fisica.unina.it Both English and Italian versions Students Teachers Researchers Together to grow-up 20

23. Actions: Experiments - World - Web International experiences to students: SKYSEF Forum at Shizuoka Kita High School, Japan ……………… Web site in English and Italian + Japanese site Virtual forum Training for Olympic games Questions to experts Experiments at school and in research labs Visiting labs 23
24. A bridge to Japan: from research to School 19 July 2012 Students from Shizuoka to Naples Meeting with students, visiting laboratories 26-29 August 2012 16 students and 3 teachers from Naples to Shizuoka: International Youth Science and Engineering Forum (SKYSEF) K. Hokusai (1760-1849) and P. Fabris (1740 – 1792) 3-6 August 2013 Students and teachers from Naples to Shizuoka: International Youth Science and Engineering Forum (SKYSEF) Open to students of all Schools Selection based on the projects presented at the Forum 24
25. “Questions to experts”: Modern and classical physics More than 50 researchers from Universities and Research Institutes available to answer questions: Laws and properties of matter The Earth and the Universe The physicist and… (applied in different fields) For each researcher: scientific profile, picture, field of interest Questions posted on the site Answers by email Direct link for in-depth analysis J-M. Folon (1934-2005) 25
26. “Virtual forum” on the Web Topics Laws and properties of matter The Earth and the Universe The physicist and… (applied in different fields) SCIENCE COMMUNICATION MODERN PHYSICS Treatment of specific arguments Historical introduction For an in-depth analysis: Lectures and discussion B. Touschek (1921-78) 26
