X-Ray Radioluminescence in Diversely Doped Multimode Silica-Based Optical Fibers

The radioluminescence (RL) response under X-rays is investigated for five different types of multimode silica-based optical fibers doped with Ge, P, Al, F, or Ce. The results indicate that all tested fibers show a measurable RL signal at dose rates from 0.1 to 15 Gy(SiO2)/s, using 10-cm-long samples and a photomultiplier-based acquisition chain. Other influences of radiation, such as radiation-induced attenuation, are discussed in order to evaluate the potential of such fiber types for radiation detection or dosimetry applications.
