Descripción
Sumario:Due to the severe radiation environment, the ATLAS experiment has chosen a compact tungsten/liquid argon forward hadronic calorimeter. The electrode design is unique and consists of hexagonally packed, tubular, thin gap electrodes $9 running parallel to the beam direction. We describe the design criteria, the novel construction methods based on sintered tungsten components, and initial high energy beam tests at CERN. (3 refs).
