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).
