Design of these toroidal magnets and of the mechanical structure of Atlas is but one contribution by Dapnia to this detector, here being mounted at Cern.
Research on the elementary constituents of the Universe is a strong focus of Irfu's activities.
The groups are actors in the ATLAS and CMS projects at the LHC and are invested in the design of future collider projects.
In the bestiary of elementary particles, the neutrino is an enigma in itself and many projects are at work with reactors, sources and accelerators, to discover its mysteries and unravel those of the new physics beyond the standard model.
The 3rd path is that of low energy with precise measurements of decay β and a measure of antimatter response to gravity.
