The Laboratory of the physics of the 2 Infinities Irène Joliot-Curie (IJC Lab) was created on January 1st 2020 from 5 laboratories :

  • CSNSM (Centre de Sciences Nucléaires et de Sciences de la Matière)
  • LAL (Laboratoire de l’Accélérateur Linéaire)
  • IMNC (Laboratoire d’Imagerie et Modélisation en Neurobiologie et Cancérologie)
  • IPN Orsay (Institut de Physique Nucléaire d’Orsay)
  • LPT (Laboratoire de Physique Théorique)

You will find more information on the history of the 5 laboratories in this document.


  • “La recherche sort de sa bulle”: two comic strips on the work of doctoral students Léonard Imbert resulting from a collaboration between the University of Paris-Saclay and the illustrator Marine Spaak.
  • Poster Gallery can be found here. These posters were designed by the laboratories that founded IJCLab, prior to the creation of the laboratory.
  • Voyages de l’infiniment grand à l’infiniment petit : a free MOOC to understand everything about the physics of the infinitely large and the infinitely small.
  • Passeport pour les deux infinis : to learn all about the book and the associated educational project.
  • Quark poker : card games to find all the constituents of matter.
  • The Elementaire review, to discover the infinitely small and the infinitely large in 9 issues.
  • D’ici au Big Bang, from Barbara Sciascia (illustration : Agostino Lacurci, French translation : Nicolas Arnaud, Marie-Hélène Schune and Monica Varvella).
  • Sciences-ACO : the museum of science and matter where you can see the ACO machine, located on the Orsay campus.
  • The COSMIX suitcase : an educational and portable detector of cosmic rays for physics teachers and their pupils.
  • L’Ecole des 2 Infinis a training programme for science teachers in high schools and preparatory classes


  • The pages of CERN, the Europen research center in high-energy physics, near Geneva
  • Synchrotron SOLEIL : a large research equipment located on the Paris-Saclay campus, open to all.
