ATLAS experiment сelebrates its 25th anniversary
World science, 02 October 2017
The ATLAS experiment turned 25 on 1 October 2017. On 1 October 1992, ATLAS submitted its Letter of Intent to the LHC Experiments Committee.
To celebrate its 25th anniversary, ATLAS is hosting six Facebook live events today, Monday 2 October 2017. Explore key locations around CERN – including the ATLAS control room, Building 40 and the ATLAS TileCal workshop – while learning about the physics, construction and history of the experiment.
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.
