Precision Crystal Calorimeters in High Energy Physics: Past, Present and Future

High Energy Physics: Past, Present and Future Ren-Yuan Zhu California Institute of Technology, Pasadena, CA 91125, USA Abstract. Precision crystal calorimeters traditionally play an important role in high energy physics experiments. In the last two decades, it faces a challenge to maintain its precision in a hostile radiation environment. This paper reviews the performance of crystal calorimeters constructed for high energy physics experiments and the progress achieved in understanding crystal’s radiation damage as well as in developing high quality scintillating crystals for particle physics. Potential applications of new generation scintillating crystals of high density and high light yield, such as LSO and LYSO, in particle physics experiments is also discussed.
