of Irradiation

| Protvino, 2012. – p. 9, figs. 4, refs.: 13. | ||
The changes of lead tungstate crystal transparency during the process of continuous exposure over about 1.200 hours in the field of gamma radionuclide 60Co source have been investigated. A crystal temperature was maintained at the level of -150С at a radiation dose rate of 0.1 Gy/h. A recovery process of the crystal transparency in the temperature range from -15 to +380С was studied just after irradiation. The work was carried out in the framework of the PANDA experiment preparation within the FAIR project in Germany.
