12 Facts About ATLAS experiment


The ATLAS experiment is designed to take advantage of the unprecedented energy available at the LHC and observe phenomena that involve highly massive particles which were not observable using earlier lower-energy accelerators.

The ATLAS experiment was proposed in its current form in 1994, and officially funded by the CERN member countries in 1995.

Construction was completed in 2008 and the ATLAS experiment detected its first single proton beam events on 10 September of that year.

ATLAS experiment Collaboration is currently led by Spokesperson Andreas Hoecker and Deputy Spokespersons Marumi Kado and Manuella Vincter.

Example, the data collected by ATLAS experiment made it possible in 2018 to measure the mass [ MeV] of the W boson, one of the two mediators of the weak interaction, with a measurement uncertainty of ±2.

One of the most important goals of ATLAS experiment was to investigate a missing piece of the Standard Model, the Higgs boson.

LHCb, an LHC ATLAS experiment dedicated to B-mesons, is likely to be better suited to the latter.

Rather than focusing on a particular physical process, ATLAS experiment is designed to measure the broadest possible range of signals.

ATLAS experiment is designed to detect these particles, namely their masses, momentum, energies, lifetime, charges, and nuclear spins.

However, the beam energy and extremely high rate of collisions require ATLAS to be significantly larger and more complex than previous experiments, presenting unique challenges of the Large Hadron Collider.

ATLAS experiment detector uses two large superconducting magnet systems to bend the trajectory of charged particles, so that their momenta can be measured.

FactSnippet No. 690,994

ATLAS experiment detector is complemented by a set of four sub-detectors in the forward region to measure particles at very small angles.
