Abstract
Very large-background radiation (neutrons, gammas, x rays) produced by intense reiativistic electron beams (10 kA, 50 MeV) requires remote operation of a sensitive optical beam diagnostic apparatus, such as imaging cameras, streak cameras, and microchannel piate detectors. Fiber-optic bundles allow such remote operation of these detectors and in addition provide great flexibility in conducting electron-beam characterization and propagation studies. Therefore, various optical fibers were examined for minimum attenuation in the UV region, maximum bandwidth, and minimum radiation response. The fibers tested were QPG giass-on-glass type, QSF-AS and plastic clad silica type, and QSF-UV and QSF-A. The core-cladding diameter varied between 183 jtrm/200 nm and 800;im/750 ,um. Attenuation was measured at 340 nm using a white-light source, narrowband filter, and radiometer. A conventional measure and cutback technique was employed. The attenuation, expressed in decibels of optical power loss per 50 ft of fiber, ranged between 2.4 and 4.8 dB for all fibers tested.
