In situ radiation testing of Ku and KS-4V optical fibers in a reactor environment

摘要

In situ radiation testing of pure-silica-core hardened (h_2-loaded and pre-irradiated) and as-drawn (untreated) optical fibers with high-Oh low-ci KU core and low-OH low-CI KS-4V core in neutron and gamma fluxes was carried out according to IR-8 reactor power. Both the radioluminescent and radiation-induced loose spectra were measured.
