LCD-ALCPG • Presentation at the ALCPG-SLAC • Meeting • Progress Report of Work at Colorado • January, 2004
LCD-ALCPG • Electromagnetic/Hadronic Calorimeter • 5x5 cm2 tile array scintillator tungsten • Alternate layers offset (picture on right) • Leads to improvement in spatial resolution added • to excellent energy resolution 11%/E1/2 • Z0->e+ e- Mass Resolution s = 1 GeV • X 2 Improvement over non-offset case. • Beginning pattern recognition of hadronic jets • Recostruction of photon energy and direction in • middle of hadronic jet. • Studying resolution of different structures versus cost.
