The prototype, designed for the containment of electromagnetic showers, was qualified on beam, first at DESY with a pure electron beam with energies up to 6 GeV and secondly at CERN with electrons up to 100 GeV (image: INFN-PV Lab)

Highly granular dual-readout calorimeters would enable a better resolution in hadron calorimetry. This summer, a prototype was tested at DESY and CERN.
The fluctuations of the electromagnetic and hadronic components of hadronic showers is one of the most limiting factors for the energy
