Abstract
With a 1 Ci Co-60-source we measured the radiation damage and its reco very in PbWO4 crystals. The method consists in measuring the anode cur rent produced in the silicon diode of a Hybrid PhotoMultiplier Tube (H PMT) during the irradiation of the crystal. At regular time intervals, we took photon counting spectra with the same HPMT. By checking the r esulting channel positions of the photoelectron peaks, we controlled t he stability of our experimental set-up. Temperature control and monit oring were achieved by forced thermostatized water circulation inside the irradiation box and by using a PT100 and two AD590 temperature pro bes. First results on irradiations of a few PbWO4 crystals are present ed and future plans are communicated.
