摘要：

Radiation-induced attenuation (RIA) at 1542 nm of fluorine-doped fibers under gamma radiation source has been investigated for different dose rates and temperatures. Both the temperature and dose rate dependencies are unusual. First, the fiber presents an enhanced low dose rate sensitivity that is favored by increasing temperature. Furthermore, in certain conditions, RIA increases with irradiation temperature, which is a very rare phenomenon. We have built a phenomenological model that shows that these behaviors can be explained considering that two color centers previously identified in the literature are responsible for RIA: inherent and strain-assisted self-trapped holes.
