Beschreibungen/Notizen

• Radiation-induced attenuation (RIA) is investigated in pure-silica-core optical fibers (PSFs) upon their pulsed-X-ray irradiation. RIA at small post-pulse times (t ≤ 0.001-0.1 s) is argued to be mainly due to inherent self-trapped holes (STHs), whereas at large times, due to strain-assisted STHs, as shown by Girard et al . Significant suppression of inherent STHs is found to occur in PSFs upon pulsed pre-irradiation with a dose of just ∼100-200 Gy. Thus, a radiation-hardening effect is revealed for the first time, which is of practical value for PSFs to be exposed to pulsed irradiation. Fiber drawing temperature T d is found to have an essential effect on RIA upon pulsed irradiation. The optimal T d -values are estimated for PSF applications at small (t < 0.01 s) and large (t > 0.01 s) post-pulse times.
