Description
In high energy and nuclear physics experiments, total absorption electromagnetic calorimeters (ECAL) made of inorganic crystals are known for their superb energy resolution and detection efficiency for photons and electrons. A crystal ECAL is thus the choice for those experiments requiring precision photon and electron measurements for their physics missions. For future HEP experiments at the energy and intensity frontiers, however, the crystal detectors used in the existing ECALs are either not bright and fast enough, or not radiation hard enough. Inorganic crystals may also be used to construct a Homogeneous Hadron Calorimeter (HHCAL) to achieve unprecedented jet mass resolution by duel readout of both Cerenkov and scintillation light. For such a calorimeter the crystal cost is a crucial issue because of the crystal volume required. This paper reports current status of crystal R&D, and discusses the next generation crystal detectors for future HEP experiments.
