We are constantly submitted to ionizing rays, either from natural or from artificial origin, visible or not. Sun light consists in visible natural rays. The sun is also a natural source of invisible rays (UV, IR)
Among natural ionizing rays, some are coming from space, and are nammed cosmic rays. Other are coming from the earth (natural radiactivity from rock). This page is dedicated to cosmic rays.
2012: 100 years of cosmic rays ; the anniversary of their discovery by V.F. Hess
-
A poster exhibition ("Le mystère des rayons cosmiques", in french) has been realized by the IN2P3 to celebrate the 100 years of cosmic rays and the anniversary of their discovery.
"Le mystère des rayons cosmiques" : une exposition IN2P3 pour fêter le centenaire de la découverte des rayons cosmiques.
Cette exposition retrace un siècle d’aventures dignes de Jules Verne. Pour tenter de percer le mystère des rayons cosmiques, les physiciens n’ont pas ménagé leurs efforts en menant leurs expériences en ballons, à bord de cargos autour du monde ou sur les plus hauts sommets... L’aventure se poursuit encore aujourd’hui avec des techniques toujours plus pointues.16 posters, A0 format. The LPSC has one copy of the exhibition.
To see the poster :http://lapp-phototheque.in2p3.fr/2012-rayonsCosmiques/
25 November - 14 December 2012 : the exhibition was installed at the lycée Marie Reynoard, Villard Bonnot
8 March -12 april 2013 : at the Lycée Condorcet, Belfort
12 April - 20 May 2013 : Lycée Follereau, Belfort

NOY: a Neutrino Observatory network project based on stand-alone air shower detector arrays
We have developed a self powered stand alone particle detector array dedicated to the observation of horizontal tau air showers induced by high energy neutrinos interacting in mountain rock. Air shower particle detection reach a 100% duty cycle and is practically free of background when compared to Cerenkov light or radio techniques. It is thus better suited for rare neutrino event search. An appropriate mountain to valley topological configuration has been identified and the first array has been deployed on an inclined slope at an altitude of 1500 m facing to Southern Alps near the city of Grenoble (France). A full simulation has been performed. A detailed cartography and elevation map was used to draw a neutrino energy dependent mountain tomography chart. The array acceptance was evaluated between 100 TeV and 100 EeV from a decaying tau air shower simulation. The effective surface is determined from the shower lateral extension at array location, and is found to be much larger than the geometrical array area. The single array yearly exposure will be 1014 cm2.sr.y at 100 PeV. The embedded data acquisition system consists of an eight channel, 12 bits, 250 MHz digitizer associated to a FPGA containing a trigger definition design, a time tagging referenced by a GPS board and a Linux core processor. PMT high voltage supplies are remote controlled via serial or USB port. Data and slow control data are stored on a flash memory. Remote control and data transfer are operated under a commercial wireless communication system. This low consumption data acquisition system is self powered via solar energy. Several independent arrays can be deployed on the same site. Other sites around the world with a similar topography can contribute to a neutrino observatory network. Some other sites are already under study. At last, special care is dedicated to the educational and outreach aspects of such a cosmic ray detector
