Radiation-hardness Studies of Cerium-doped Fused-silica Optical Fibers
 
Show general info
Content: We report on the radiation-hardness of cerium-doped scintillating fused-silica fibers for detector applications in particle and nuclear physics. Three types of fibers with the same coaxial 15-um-thick doped ring structure, but different cladding and buffer materials, were irradiated with varying dose rates up to 1,500 kGy at the gamma irradiation facilities at the Sandia National Laboratory, University of Maryland, and at the Department for Fusion and Nuclear Safety Technologies (ENEA) in Rome, Italy. Clear-fused silica fibers were also included in these irradiation campaigns as benchmark. We find that the radiation-induced attenuation grows with integrated dose obeying the well-established power law. This continued R&D project aims to achieve sufficiently robust and bright scintillating fibers that can survive the harsh radiation environments at the future high-intensity experiments.
