DEGRADATION FEATURES OF BAF2 SCINTILLATORS UNDER RADIATION AND MAGNETIC-FIELDS

Degradation features of BaF2 scintillators have been examined in combi ned gamma- and n-radiation and strong magnetic fields. Created radiati on defects have been investigated by optical magnetooptical, and ODMR techniques. It is shown that the magnetic field has no selective actio n on defects of different structure. The magnetic field slightly dimin ishes the efficiency of creation of impurity color centers. The decrea se of the creation rate at a magnetic field of B = 1T does not exceed 10%. The nature of these radiation defects in BaF2 scintillators obtai ned by different technologies is discussed.
