Dual-readout calorimetry with a Mo-Doped PbWO4 electromagnetic section

A first attempt to use an electromagnetic calorimeter prototype made of Mo-doped PbWO
₄
crystals in view of the possible application of such a detector in dual-readout hybrid calorimetry is described. The detector is made of a matrix of 7 crystals, read out on both sides with photodetectors, equipped with UV and yellow filters each, in order to separate the scintillation and Cherenkov components using their spectral properties. These two components can also be separated using the time structure of the signal. For this purpose the PMTs were read out with Domino Ring Samplers. Data were taken with electron beams of different energies at the H8 beam line at CERN.
