Transient Attenuation In Connectors To PCS Fibers And In Glass-On-Glass Fibers Induced By Pulsed X-Rays

Using Sandia Laboratories Hermes Ii X-Ray Pulser, We Have Measured The Transient Attenuation Of Connectors To Pcs Fiber Prepared With Raychem Fibersleeves® And Of Glass-On-Glass Silica Core Fiber (Raychem Type Vsc) Induced By 50 Nanosecond X-Ray Pulses With Total Dose Of 5 Krads. No Significant Losses Were Induced In The Connectors Either At 23°C Or At -55°C, Thus Qualifying Them For Use In A High Radiation Environment. The Peak Transient Attenuation Measured For The Fiber With 200 Micrometer Core Diameter At -55°C (7.2 Db/Km/Krad) Is Significantly Lower Than For Any Other Commercially Available Fiber At That Temperature.
