ATLAS is one of two general-purpose detectors at the Large Hadron Collider (LHC). It investigates a wide range of physics, from the search for the Higgs boson to extra dimensions and particles that could make up dark matter. Although it has the same scientific goals as the CMS experiment, it uses different technical solutions and a different magnet-system design. Beams of particles from the LHC collide at the centre of the ATLAS detector making collision debris in the form of new particles, which fly out from the collision point in all directions. Six different detecting subsystems arranged in layers around the collision point record the paths, momentum, and energy of the particles, allowing them to be individually identified. A huge magnet system bends the paths of charged particles so that their momenta can be measured.

JINR was involved in the preparation of the international ATLAS experiment at the stage of preliminary research and development, and became one of its major participants. JINR staff members made a significant, and sometimes decisive contribution to the development, design, production, assembly and commissioning of virtually all main subsystems of the ATLAS detector. At the moment, JINR takes an active part in the ATLAS Upgrade project.

The Conference dedicated to the 25th anniversary of participation of JINR in the ATLAS experiment was held by the Joint Institute for Nuclear Research in April 2017.
