    Fermilab's neutrino test

    Scientist Ioanis Kourbanis checks a beam-focusing horn for the MiniBooNE experiment conducted by the Fermi National Accelerator Laboratory, or Fermilab, near Chicago. The goal of the experiment is to determine how many types of neutrinos exist. Neutrinos are electrically neutral particles of very little mass that are created during nuclear reactions.

    Medea detector

    Detail of the Medea detector at South National Laboratories, in Catania, Italy. The Medea detector is used to measure gamma rays and particles produced by collisions between heavy ions. Detection of gamma rays and other extremely high-energy particles enables researchers to obtain information about the collision's first moments, in which nuclear matter reaches conditions of extremely high density and temperature.

  • scintillating fibers

    scintillating fibers

    The peculiarity of the scintillating fibers shown in this detector is that they emit light when charged particles pass through them, a characteristic that makes them useful as components in particle detectors. Italy's National Institute for Nuclear Physics (known as Infn) has developed an extremely advanced system of scintillating fibers in cooperation with the firm Pol.Hi.Tech., a specialist in nuclear-medicine equipment. Recently, scintillating fibers also have been used to make high-tech cloth for fashion clothing.
