Abstract

In this paper, fibers with different depths of hermetically coated carbon are hydrogen loaded and radiated, and it’s found that too thick of carbon layer around fiber can’t bring best radiation-resistant properties, because the thick carbon layer would make the entering of hydrogen difficult although it can help to stop the hydrogen escaping. We also research the duration of saturated hydrogen loading under the temperature of 60°C and 100°C respectively, and it’s found that after 120h and 48h, the fibers’ photo sensitivities tend to be flat. We also reload hydrogen into the fibers which have been loaded once, and these fibers are etched then, this help us to deep understand the mechanism of hydrogen loading for the fiber gratings.
