Laboratoire de physique des 2 infinis Irène Joliot-Curie is a French multidisciplinary research laboratory specializing in the physics of the very large and the very small, linking particle physics experiments with nuclear physics and astrophysics observations. The laboratory operates within the framework of national and international institutions and participates in major experimental collaborations with facilities and agencies across Europe and beyond. Its work connects historical legacies of French science with modern projects hosted at national centers and transnational infrastructures.
The laboratory emerged from reorganizations involving Université Paris-Saclay, Université Paris-Sud, Centre national de la recherche scientifique, and the former Institut national de physique nucléaire et de physique des particules structures, inheriting personnel, groups, and assets from institutions associated with figures such as Irène Joliot-Curie and technological centres like Orsay campus. Its formation reflects policy decisions influenced by ministries linked to French research funding and European frameworks such as Horizon 2020 and predecessors. Over time the laboratory has contributed to projects at facilities including European Organization for Nuclear Research, CERN, Institut Laue–Langevin, and Laboratoire Léon Brillouin, while interacting with national agencies like Agence nationale de la recherche and organizations such as Commissariat à l'énergie atomique et aux énergies alternatives.
Research topics span experimental and theoretical work in particle physics, nuclear physics, hadron spectroscopy, neutrino physics, astroparticle physics, cosmology, and accelerator physics. Groups address detector development for experiments at Large Hadron Collider, neutrino programs at JUNO, Super-Kamiokande, and reactor experiments involving Institut Laue–Langevin or BR2 reactor collaborations. The laboratory hosts teams working on quantum detectors, cryogenics, silicon sensors, and theory groups engaged with models from Standard Model extensions to quantum chromodynamics, linking to initiatives like International Linear Collider studies and Einstein Telescope preparatory work. Cross-disciplinary efforts connect to astrophysics consortia, Planck legacy analysis, and multimessenger campaigns with observatories such as Fermi Gamma-ray Space Telescope and IceCube Neutrino Observatory.
The laboratory is organized into thematic teams and administrative units aligned with university departments and national institutes such as CNRS and IN2P3. Management interfaces with governance bodies including university councils like Conseil d'administration de l'Université Paris-Saclay and oversight from funding bodies such as European Research Council and national ministries. Scientific steering boards coordinate interactions with experiments at facilities like CERN, ITER (for related diagnostics), and infrastructure projects tied to Synchrotron SOLEIL and European Spallation Source. Internal committees handle doctoral programs linked to graduate schools such as Ecole Doctorale Paris-Saclay.
On-site laboratories and cleanrooms support instrumentation work for detectors, electronics, and cryogenics, with dedicated beamlines and calibration setups used in collaboration with Synchrotron SOLEIL, Institut Laue–Langevin, and European Synchrotron Radiation Facility. The laboratory maintains computing clusters interoperable with grids like Worldwide LHC Computing Grid and cloud resources coordinated with CERN IT services and national infrastructures such as GENCI. Specialized workshops fabricate components compatible with accelerators at CERN, European XFEL, and isotope production facilities including GANIL and ISOLDE. Safety and radioprotection comply with regulations from authorities like Autorité de sûreté nucléaire.
The laboratory is a partner in major international collaborations including ATLAS, CMS, LHCb, ALICE, and neutrino collaborations like Double Chooz and DUNE preparatory networks. It engages with European research programs such as Erasmus Mundus for mobility and with agencies including CEA and IN2P3. Industrial partnerships involve companies in the microelectronics and cryogenics sectors and technology transfer offices tied to SATT Paris-Saclay and CNRS Innovation. The laboratory contributes to consortia for large infrastructures like European Research Infrastructure Consortium projects and links with space agencies such as CNES and ESA for instrumentation in space missions.
Academic programs include doctoral supervision within Université Paris-Saclay and collaborations with engineering schools such as École Polytechnique and CentraleSupélec for internships and joint courses. The laboratory supports postdoctoral fellows funded by Marie Skłodowska-Curie Actions and national grants from Agence nationale de la recherche and European Research Council fellowships. Outreach and training activities involve summer schools associated with CERN, topical workshops with Institut Henri Poincaré, and exchanges with institutions like Imperial College London, Massachusetts Institute of Technology, and University of California, Berkeley.
Key achievements include contributions to discovery and precision measurements at Large Hadron Collider experiments, detector innovations for ATLAS and CMS upgrades, and leadership in neutrino detector R&D for projects like DUNE and JUNO. The laboratory has produced influential results cited in collaborations with Planck, Pierre Auger Observatory, and IceCube Neutrino Observatory, and has developed instrumentation adopted by facilities such as European XFEL and Synchrotron SOLEIL. Recognition of members includes awards and fellowships from institutions like Académie des sciences, European Physical Society, and national orders. Its legacy continues through participation in next-generation projects including High-Luminosity LHC, Einstein Telescope, and multinational initiatives coordinated by CERN and ESA.
