As part of a collaborative experimental High Energy Physics experiment at the LHC Facility, CERN Laboratory, Geneva Switzerland, a group of US institutions has accepted the responsibility for constructing a large portion of the calorimeter for this experiment. This device is referred to as the Tile Calorimeter. The Tile Calorimeter has three major elements, a large center section (Barrel), and two end sections (Extended Barrel). The US group will be responsible for the construction of one of these extended barrel sections. All of the components that are required to construct this device will be fabricated in the US over a period of three years commencing in 1998. Another similar element and the barrel element will be constructed in both eastern and western Europe by parallel groups. The extended barrel is a cylindrical device approximately 8.5 meters (28 ft.) OD x 4.5 meters (14 ft.) ID, made up of 64 wedges. Each of these wedges (see Attachment 1) is constructed by bolting submodules to a strongback girder. Each submodule is constructed of a series of sheets that are welded and glued together. This document summarizes the characteristics and specifications of these steel sheets. The Tile Calorimeter is the return path for the magnet flux of the ATLAS internal superconducting 2T solenoid, therefore its steel magnetic properties are important.
