摘要：

The primary concern for implementing amorphous fused silica (alpha-SiO2) fiber optic sensors in a nuclear environment is the radiation-induced attenuation (RIA) of the light signal due to the formation of radiation-induced color centers. In addition, Bragg grating sensors drift under irradiation due to radiation-induced compaction of the alpha-SiO2 structure. This work provides new data regarding RIA and radiation-induced compaction of alpha-SiO2 samples irradiated to a fast neutron fluence of 2.4 x 10(21) n/cm(2) at temperatures of 95, 298, and 688 degrees C. Results show that RIA may be approaching saturation for the range of photon energies evaluated in this paper and that the hydroxyl content has a significant impact on RIA when the irradiation temperature is increased to 688 degrees C. A model was developed for predicting radiation-induced compaction, and the resulting signal drift for Bragg grating sensors, as a function of neutron fluence and temperature.
