Descripción
Sumario:The hadronic performance of a Dual-Readout calorimeter consisting of a crystal em section and a hadronic section read out with two types of optical fibers is studied with 200 GeV π+. The em fraction of hadronic showers developing in this calorimeter system is determined event by event from the relative amounts of Cherenkov light and scintillation light produced in the shower development. Data are presented for two types of crystals (PbWO4 and BGO), each of which offers unique opportunities in this respect. The information obtained with this technique may lead to an important improvement in the hadronic calorimeter performance.
