Laboratoire de Physique Subatomique et de Cosmologie is a multidisciplinary research laboratory located in Grenoble, France, affiliated with the Centre national de la recherche scientifique, Université Grenoble Alpes, and the Commissariat à l'énergie atomique et aux énergies alternatives. The laboratory conducts experimental and theoretical studies spanning particle physics, astroparticle physics, cosmology, and nuclear physics, and participates in major international projects and observatories. It maintains ties with accelerator facilities, underground laboratories, and space missions, and contributes to instrumentation, data analysis, and theoretical modeling.

History

The laboratory traces its institutional origins to French research centres active during the 20th century such as the CNRS, CEA, and Université Grenoble Alpes predecessor institutions like the Institut National Polytechnique de Grenoble. Its development was influenced by international projects including CERN experiments, Gran Sasso National Laboratory initiatives, and collaborations with the European Space Agency and National Aeronautics and Space Administration. Key milestones include participation in experiments at Large Hadron Collider, involvement in neutrino research connected to Super-Kamiokande and Sudbury Neutrino Observatory, and contributions to cosmic microwave background studies related to Planck (spacecraft) and WMAP. Over time the laboratory expanded instrumentation work linked to facilities such as the Institut Laue–Langevin and the European Synchrotron Radiation Facility.

Research Areas

The laboratory’s research covers experimental particle physics with links to ATLAS, CMS, and LHCb, and astroparticle physics projects like Pierre Auger Observatory, IceCube, and ANTARES. In neutrino physics it connects to T2K, NOvA, and DUNE. Cosmology work relates to Planck, Euclid, and large-scale surveys such as Sloan Digital Sky Survey. Nuclear physics and detector development tie to SPIRAL (facility), GANIL, and ISOLDE. Theoretical groups engage with models rooted in Standard Model, Supersymmetry, and inflationary scenarios, interfacing with computational projects linked to Lattice QCD, Monte Carlo method, and collaborations with Institut de physique théorique groups.

Facilities and Instrumentation

Experimental infrastructure includes cleanrooms and electronics laboratories used for building detectors compatible with ATLAS, CMS, XENON, and EDELWEISS. Cryogenic facilities support work for projects associated with Planck instrumentation and bolometer development similar to that used by Herschel. The laboratory operates testing benches for photodetectors used in Super-Kamiokande-like and IceCube-style instrumentation, and collaborates with accelerator facilities such as CERN, ESRF, and ILL for beam tests. Underground experiment support connects to Modane, Gran Sasso National Laboratory, and Boulby Underground Laboratory. High-performance computing resources support simulations comparable to those at Centre de calcul de l'IN2P3 and coordination with Compute Canada-style centers.

Collaborations and Partnerships

The laboratory is a partner in multinational consortia including CERN collaborations, ESA missions, and global observatory networks like Pierre Auger Observatory and IceCube. It maintains bilateral links with institutions such as CEA, CNRS/IN2P3, Université Paris-Saclay, Imperial College London, University of Oxford, Massachusetts Institute of Technology, and Princeton University. Regional partnerships include cooperation with Grenoble Alpes Métropole, CEA Grenoble, and European projects funded through the European Commission frameworks. The laboratory contributes to long-baseline collaborations including DUNE and T2K, and instrumentation consortia for space missions like Euclid and Planck.

Organization and Personnel

Governance follows a joint unit model shared by CNRS, Université Grenoble Alpes, and CEA, with scientific boards and technical committees interacting with groups from IN2P3 and regional universities such as Université Joseph Fourier (now part of Université Grenoble Alpes). Senior researchers have included principal investigators active in collaborations with CERN experiments and space missions; technical staff have backgrounds tied to ESRF and ILL projects. The laboratory hosts postdoctoral researchers and doctoral candidates registered through doctoral schools like those of Université Grenoble Alpes and participates in national recruitment via CNRS and CEA procedures.

Education and Outreach

Educational activities include doctoral training within the doctoral schools of Université Grenoble Alpes, master’s level courses linked to Grenoble INP, and internships for students from institutions such as École normale supérieure de Lyon and École Polytechnique. Outreach programs engage the public through events associated with Fête de la Science, collaborations with science museums such as the Musée de Grenoble, and public lectures in partnership with European Space Agency outreach teams and CERN visitor programmes. The laboratory contributes to teacher training initiatives coordinated with regional academic authorities and participates in international summer schools including those organized by ICTP and Les Houches Summer School.
