Laboratory of the Physics of the two infinities Irène Joliot-Curie (IJCLab)

Research unit


The Laboratory of the Physics of the two infinities Irène Joliot-Curie (IJCLab) was born in 2020 from the merger of 5 research units: CSNSM, IMNC, IPNO, LAL, LPT. Its scientific activities are structured into 7 scientific poles: 1- Astroparticles, Astrophysics and Cosmology, 2- Accelerator physics, 3- High Energy Physics, 4- Nuclear Physics, 5- Theoretical Physics, 6- Energy and environment, 7- Health. They are supported by an Engineering Pole which brings together high-expertise technical services, structured into four departments in the fields of electronics, IT, instrumentation and mechanics. This set represents a unique potential for the design, development and use of the instruments necessary for the scientific challenges of the decades to come (accelerators and detectors). The presence of a vast set of research infrastructures and technological platforms (ALTO, MOSAIC, Laserix, Supratech), is also an essential characteristic of the IJCLab.
