Electromagnetic/Hadronic Calorimeter
5x5 cm2 tile array scintillator tungstenAlternate layers offset (picture on right)Leads to improvement in spatial resolution addedto excellent energy resolution 11%/E1/2
Z0->e+ e- Mass Resolution GeVX 2 Improvement over non-offset case.Beginning pattern recognition of hadronic jetsRecostruction of photon energy and direction in middle of hadronic jet.
Studying resolution of different structures versus cost.
