Abstract:

Using C0 60 gamma ray and fast neutron flux from a research reactor, in situ measurements of radiation induced optical attenuation have been conducted to characterize the radiation response of pure-silica core fibers and doped-silica core fibers. It has been revealed that pure-silica core fibers fabricated by Modified Rod-in-Tube method have much higher radiation resistivity than GeP-and BFP-doped-silica core MCVD fibers. Among the pure-silica core fibers, high-OH content grade has shown the highest resistivity in short wavelength region, whereas OH-free grade is useful in long wavelength region. Radiation hardening was observed in the high-OH content fiber during the test by long-term irradiation on pure-silica core fibers. Author
