Scintillators and Cherenkov crystals are widely used to build compact electromagnetic calorimeters (ECALs), but their lattice effects are usually neglected. When a charged particle impinges along crystallographic planes or axes, it experiences a coherent interaction with the Coulomb field of the lattice atoms averaged along the plane or axis [1]. At high energies, in high-Z crystals, this interaction results in a harder radiation emission and enhancement of the pair production probability, which significantly accelerates the shower development [2].
The ORiEnted calOrimeter (OREO) project, within the DRDCALO collaboration, exploited these effects to realize the first prototype of an ultra-compact ECAL composed of two layers of 3x3 oriented PWO-UF crystals [3]. The OREO calorimeter is the outcome of seven years of intense R&D studies and has achieved significant results in advancing the understanding of particle interactions in ECALs [4].
This contribution presents an overview of the R&D phase of the OREO project; the performance of the OREO calorimeter as obtained in several beam tests performed at CERN PS and SPS, and the prospects for the future application of this novel technology.
