Laboratoire d’Annecy-le-Vieux de Physique des particules
CNRS/IN2P3 laboratory (since 1976) and part of the Université de Savoie (since 1995)

IN2P3 and its laboratories
• IN2P3 is a CNRS institute coordinating research in nuclear physics, particle physics and astroparticles in partnership with universities and the CEA (like Saclay).
• About 20 laboratories in France.
LAPP history
4
1976: LAPP founded by Marcel Vivargent (1926-2010) and a group of physicists from Orsay wanting to be closer to CERN.
LAPP has been contributing to important historical experiments and developments in particle physics like UA1 discovering W and Z bosons (C.Rubbia physics Nobel prize in 1984) or wire chambers (G.Charpak physics Nobel prize 1992) or LHC (Higgs, Englert physics Nobel prize 2013)

Evolution
ATF2 Annecy Workshop 5
New subject, Astroparticles: gravitational waves, high energy cosmic rays, dark matter, antimatter in the universe. Experiments on far sites (other than CERN…) : Italy, California, Namibia, Japan, International Space Station (ISS)
1991: LAPP grows…
1995: LAPP becomes Mixed research Unit (CNRS and Université de Savoie).
• LEP experiments (e+e-)
2008: LHC starts at CERN
18/03/2014
2013: LAPP grows with the Maison de la Mécatronique
Experimental physicists…• Within international collaborations, LAPP researchers contribute
to the design and/or construction of detectors for experiments often gigantic, long term and they analyse the recorded data to verify or counter theories and discover new phenomena.
18/03/2014 ATF2 Annecy Workshop 6
• On accelerators like CERN (ATLAS, LHCb) or Stanford (BaBar)
• On far sites or in space : VIRGO (Pise), OPERA (Gran Sasso), HESS (Namibie), AMS (Space station).
