Institute of research into the fundamental laws of the Universe

CERN has always been one of Irfu’s main partners and several of the institute’s employees regularly go there or even stay there for several years. The Irfu office at CERN offers valuable support when setting up or carrying out experiments. In addition to providing the essential interface role with the CERN technical teams, the office also has a mechanical workshop. In 2017, for the ATLAS MFT project, it was equipped with a dust-free room and a “MAM” machine for micron precision assembly, automatic testing and laser welding of the detection ladders made of CMOS sensors.
