Abstract

We have made light-transmission measurements of high-purity, radiation-resistant, Raychem and Heraeus optical-fiber samples that had been exposed to 10- and 100-krad doses from 0.5-MeV-electron pulses. An electron beam from a Febetron 706 x-ray machine produced a radiation source that emitted the above doses in single pulses with a full-wave half maximum (FWHM) of approximately 1.5 ns. Light sources for the transmission measurements (a mercury/krypton-vapor flashlamp and a laser diode) provided spectral data for a continuous-wavelength band from 420 to 760 nm and a single wavelength at 820 nm. The light beam was dispersed by a grating and recorded by a streak camera. We gathered data at times ranging from approximately 3 ns to 1 μs after the radiation pulse.
