Scintillating Fibers for Particle Physics Experiment - On-line Induced Absorption Measurement in Gamma Radiation Field

Popis výsledku v původním jazyce

Changes in the radiation-induced transparency of scintillating and wavelength-shifting fibers were studied by means of on-line-induced absorption coefficient measurement during and after gamma irradiation. It was found that the main contribution to radiation damage was caused by reactions between luminescent molecules. The time dependence of the radiation-induced absorption coefficient was analyzed in the broad spectral range (420 - 735 nm) and compared with kinetic models of the processes of absorptioncenter build-up and recovery. The latter has been recently published for these fibers and a lower dose rate in the range of 0.002- 0.01 Gy s-1 . Good agreement was reached between the low-dose and the presented high-dose measurements (dose rate 4.2 Gy s-1 ). The parameters calculated in this kinetic model are applicable to prediction of the fiber behavior in particle physics experiments.
