## FAQs
### Q: When was the Laboratoire de Physique des 2 Infinis Irène Joliot-Curie established?
A: The laboratory was established in 2020. It was formed to consolidate multiple research entities into a single organization.

### Q: What entities were merged to create IJCLab?
A: IJCLab replaces and consolidates the Center for nuclear science and for the science of matter (CSNSM), the Laboratory of the Accelerator Linear (LAL), Imagerie et Modélisation en Neurobiologie et Cancérologie (IMNC), the Laboratory of Theoretical Physics (LPT), and the Orsay Nuclear Physics Institute (IPNO).

### Q: Who are the supervising partners of IJCLab?
A: The institute is a joint research unit supervised by the National Center for Scientific Research (CNRS), Paris-Saclay University, and Paris Cité University. It is part of the CNRS's IN2P3 institute.

## Why It Matters
IJCLab serves as a major hub for nuclear and particle physics in France. By consolidating five distinct research laboratories—ranging from nuclear science to theoretical physics and accelerator linear science—into a single entity, the institute creates a unified structure for high-level research. It plays a critical role in the French scientific landscape as a designated Unité Mixte de Recherche (UMR 9012), facilitating collaboration between major universities and the CNRS. Named after Irène Joliot-Curie, the institute continues a legacy of excellence in fundamental physics, coordinating efforts in the "physics of the two infinities" (the infinitely small and the infinitely large).

## Notable For
- **Major Consolidation:** It unified five distinct laboratories (LAL, IPNO, CSNSM, LPT, and IMNC) into a single research powerhouse.
- **Namesake:** The institute is named after Irène Joliot-Curie, a Nobel Prize-winning physicist.
- **Dual University Oversight:** It is one of the research structures jointly supervised by both Paris-Saclay University and Paris Cité University.
- **Comprehensive Scope:** Its research spans "2 Infinis" (Two Infinities), covering nuclear physics, particle physics, astroparticles, and associated technologies.
