Optical fibers degrade in radiation fields, but exhibit some recovery once removed. Study of repeated irradiations are difficult to find in the literature. We find that a UV-blue optical wavelength shifting fiber exhibits permanent degradation, the recovery is incomplete, and an interesting two step damage process that appears to affect which wavelengths are darkened at different rates. © 2020 IEEEeninfo:eu-repo/semantics/closedAccessConference Object10.1109/NSS/MIC42677.2020.95079202-s2.0-85124705573N/A
