Abstract

The electromagnetic calorimeter of the PANDA detector at the future Facility for Antiproton and Ion Research is one of the central components to measure high-energy photons over a wide dynamic range down to a few tens of mega–electron volts. The calorimeter comprises almost 16 000 PWO-II crystals of 200 mm length with high quality standards in optical performance, light output, and radiation hardness. The running mass production has passed more than 7000 crystals. The observation of stimulated recovery even of cooled crystals by illumination with external light sources integrated into the detector modules has opened up a new design concept for PANDA and future calorimeters.
