LAPP 18/03/2014ATF2 Annecy Workshop3

LAPP history : LAPP founded by Marcel Vivargent ( ) 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/ : 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).
