Laboratoire d’Annecy-le-Vieux de Physique des particules CNRS/IN2P3 laboratory (since 1976) and part of the Université de Savoie (since 1995) Most slides taken from J.P.Lees vice- director of LAPP (translated by A.Jeremie)
18/03/2014ATF2 Annecy Workshop2 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) 18/03/2014ATF2 Annecy Workshop
Evolution ATF2 Annecy Workshop5 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) 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. 18/03/2014ATF2 Annecy Workshop6 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).
