    "abstract": "The electromagnetic calorimeter of PANDA at the FAIR facility will rely on an\noperation of lead tungstate (PWO) scintillation crystals at temperatures near\n-25 deg.C to provide sufficient resolution for photons in the energy range from\n8 GeV down to 10 MeV. Radiation hardness of PWO crystals was studied at the\nIHEP (Protvino) irradiation facility in the temperature range from room\ntemperature down to -25 deg.C. These studies have indicated a significantly\ndifferent behaviour in the time evolution of the damaging processes well below\nroom temperature. Different signal loss levels at the same dose rate, but at\ndifferent temperatures were observed. The effect of a deep suppression of the\ncrystal recovery process at temperatures below\n  0 deg.C has been seen.",
