ATLAS experiment
The design was a combination of the two previous experiments, and also benefitted from the detector research and development that had been done for the Superconducting Super Collider. The ATLAS experiment was proposed in its current form in 1994, and officially funded by the CERN member countries in 1995. Additional countries, universities, and laboratories have joined in subsequent years. Construction work began at individual institutions, with detector components then being shipped to CERN and assembled in the ATLAS experiment pit starting in 2003.
