Electron paramagnetic resonance (EPR) results on samples X-ray irradiated at 5 kGy(SiO2), employing different temperatures and dose rates, are reported and discussed. [...]

The transient radiation-induced attenuation (RIA) of two different versionsof pure-silica-core (PSC) multimode optical fibers (so-called“solarization-resistant”fibers) exposed to nanosecond 1 MeV X-ray pulses are investigated.On-line RIA spectra measurements at both room temperature (RT) and liquidnitrogen temperatures (LNT) in the range 1–3.5 eV are performed. Followingthe RIA kinetics, the properties of the metastable defects that are bleachedjust after the pulse are discussed. [...]

We investigated the online radiation-induced attenuation of two single-mode optical fibers (OFs) that were X-rays irradiated with doses up to 100 kGy(SiO$_{2}$) at room temperature at 10.7 Gy/s. One of the two samples was doped only with phosphorous, whereas the other was codoped with phosphorous and cerium. [...]

We demonstrate the feasibility of resetting and reusing dosimeters exploiting the measurement of the infrared radiation-induced attenuation (IR-RIA) in phosphosilicate optical fibers (OFs) to provide point or distributed dose measurements in radiation environments. To bleach the room temperature stable IR-RIA, we used the photobleaching (PB) phenomenon. [...]

Point or distributed optical fiber (OF)-based dosimeters can exploit the observed linear dependence of the radiation-induced attenuation (RIA) at 1550 nm in phosphosilicate OFs to monitor the total ionizing dose (TID). The temperature dependence of the radiation sensitivity coefficients at 1550 nm (expressed in dB km$^{-1}$ Gy$^{-1}$) of three phosphorus-doped single-mode OFs has been investigated between -80 °C and 300 °C for TID ranging from 1 Gy to 1 kGy(SiO$_2$).

We systematically explore the suitability of two radiation-sensitive multimode optical fibers (OFs) with either P or GeP-doped cores to serve as the sensing elements in point or distributed dosimeters. To this end, we measured the dependences of their spectral radiation-induced attenuation (RIA) in the visible and near-infrared (near-IR) domain (400–2100 nm) up to total ionizing dose (TID) of 5 kGy(SiO2) while varying the irradiation temperature from −80 °C to +80 °C and the dose rate between 1 mGy(SiO2)/s and 10 Gy(SiO2)/s.

This article presents a new prospect for radiation detection exploiting the high radiation sensitivity of an ultralow-loss pure-silica core optical fiber (ULL-PSCF). This fiber exhibits very high transient X-ray radiation-induced attenuation (RIA) levels from UV to IR during irradiation, while its RIA quickly returns to a low permanent level after irradiation.
