ATLAS recognises its best suppliers

The ATLAS experiment, as any other experiment at CERN, will become a reality thanks to a large international collaboration partnership. The industrial suppliers for the components all over the world play a major role in the construction of this gigantic jigsaw for the LHC. And sometimes they perform so well, that their work deserves real special recognition. This is the case for Kawasaki Heavy Industries and Toshiba Corporation, producers of the Liquid Argon Barrel Cryostat and of the Superconducting Central Solenoid, respectively.
With these awards, the ATLAS Collaboration wants to congratulate Kawasaki and Toshiba for fulfilling the high expectations of the project: both components have been built with outstanding quality and respect fully the tight mechanical tolerances. They have passed successfully strict acceptance tests in the factories and at CERN. The spokesperson of ATLAS also highlighted the fact that these two pieces were delivered on time to CERN.
The Liquid Argon barrel cryostat, manufactured by Kawasaki, is a cryogenic pressure vessel of exceptional dimensions (5.55 meters in diameter, 6.81 meters in length) that houses the electromagnetic barrel calorimeter and the central solenoid. It was designed and constructed under the responsibility of Brookhaven National Laboratory (BNL), as an in-kind contribution of the U.S. collaborators in ATLAS. The ultra-thin superconducting solenoid, manufactured by Toshiba, has a bore of 2.4 meters and is 5.3 meters long, and will provide a 2 Tesla particle bending field for the inner tracking detector. It is an in-kind contribution of the Japanese ATLAS collaborators, and was designed and constructed under the responsibility of KEK.
