On radiation damage of scintillating organic fibres in dependence on energetic electron bombardment

New experimental results on in-situ observations of degradation of scintillating light yield and on time-compressed ageing and recovery studies of organic blue and green scintillating fibres generated by 16 MeV electron irradiation are reported. Only for low current densities the observed in-situ de...

More Information
Summary:New experimental results on in-situ observations of degradation of scintillating light yield and on time-compressed ageing and recovery studies of organic blue and green scintillating fibres generated by 16 MeV electron irradiation are reported. Only for low current densities the observed in-situ degradation has a nearly linear decrease. Typical self annealing effects can be characterized by a logarithmic law. Total recovery of optical properties for blue and green scintillators does not occur for energy doses above 10 Mrad and 20 Mrad, respectively.
