The Laboratoire Leprince-Ringuet is a part of the IN2P3 institute ("Institut National de Physique Nucléaire et de Physique des Particules") which is the nuclear and particle physics department of the CNRS french agency for scientific research ("Centre National de la Recherche Scientifique"). It is located on the l'Ecole polytechnique campus in Palaiseau (Essonne, France). The laboratory is involved in both particle and astroparticle physics research programmes with participations to:

particle physics experiments on electroweak interactions (CMS, ILC-CALICE), neutrinos (T2K), and quark-gluon plasma (PHENIX, CMS). These experiments take place at CERN (Genève Switzerland), Tokai (Japan) and RHIC (Brookhaven, New York, USA).

The astrophysics programme deals with high energy gamma ray detection (HESS, in Namibia), a satellite experiment (Fermi Gamma-ray Space Telescope) and the next generation gamma-ray observatory: CTA.
