Abstract:

The effects of gamma ray and pulsed electron irradiation on the optical performance of fiber optic waveguides and glasses potentially relevant to fiber systems have been measured. Permanent and transient absorption, luminescence, scattering and index of refraction measurements are reported. The mechanisms responsible for the optical degradation in commercial and low loss fibers have been investigated. Initial attempts at radiation protection of fiber glasses using cerium doping are discussed. Author
