ATLAS CALORIMETERS / FULL SCALE TEST IN Bd.185

The cooling systems of the drawers and of the front-end electronic crates in the ATLAS Tile and  LAr calorimeters are foreseen to operate with water at sub-atmospheric pressure, using the so-called Leakless Cooling System v.2. Though this system is already running in many experiments at CERN and outside, the huge dimension of ATLAS and severe environment (inaccessible, high radiation, magnetic field) call for a full-scale demonstrator in order to check our calculations, to test the selected components and to develop the control system.
