Crystal Calorimeters in the Next Decade

Crystal calorimeter has traditionally played an important role in precision measurement of electrons and photons in high energy physics experiments. Recent interest in calorimeter technology extends its application to measurement of hadrons and jets with dual readout. Potential application of new generation scintillating crystals of high density and high light yield, such as cerium doped LSO and LYSO, in high energy physics experiments is described. Candidate crystals for the homogeneous hadronic calorimeter concept are also discussed.
