  1. 1.

    A tradition of collaboration with Japan ...more than 20 years

    long Giovanni De Lellis Università “Federico II” and INFN Napoli 1
  2. 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

    The first tau neutrino observed in Naples Identified by seeing

    its interaction with the tau lepton production (tau leaving only 10-13 sec) 7

    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

    “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
