Abstract

A prototype lead-liquid-argon electromagnetic calorimeter with parallel plates and Accordion geometry has been equipped with high speed readout electronics and tested with electron and muon beams at the CERN SPS. For a response peaking time of about 35 ns, fast enough for operation at the future hadron colliders, the energy resolution for electrons is 9.6%/√E[GeV] with a local constant term of 0.3% and a noise contribution of 0.33 E[GeV]. The spatial accuracy achieved with a detector granularity of 2.7 cm is 3.7mm E[GeV] and the angular resolution 12 mrad at 60 GeV.
