Fast radiation-induced attenuation in single-mode optical fibres
Single-mode optical fibres (SMOF) with Ge-doped silica cores have been subjected to nanosecond pulses of 8 MeV electrons and X-rays at up to 5 Gy/pulse. The radiated-induced attenuation was studied at 630 nm with nanosecond resolution. Results suggest that SMOF and multimode optical fibres (MMOF) of similar composition exhibit comparable susceptibilities to ionising radiation.
