4. Radiation Monitoring With Radiosensitive Pure-Silica Core Ultralow Loss Optical Fiber

Abstract

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. In this work, the RIA kinetics are investigated exposing the ULL-PSCF to multiple short irradiation runs at different dose rates. Preirradiation has been demonstrated to stabilize the response of the optical fiber (OF) and to make it even more appealing for radiation detection and monitoring. After this preirradiation treatment, the RIAs at 620 and 1310 nm, in particular, exhibit anon/off behavior: the permanent RIA is nearly zero in-between irradiation and the transient RIA quickly increases up to the dB/m level when the ULL-PSCF is exposed to X-rays. By varying the fiber length and adapting the interrogation setup, large ranges of doses and dose rates can be detected with this new class of OFs.

Abstract

The dosimetry performances of a nitrogen‐doped core (diameter of 8 μm) optical fiber, before and after 100 kV X‐Ray preirradiation treatments, up to cumulated dose of 1 MGy(SiO2), to highlight their effects on the radiation‐induced luminescence (RIL), are investigated. The RIL reproducibility versus dose rate calibration curves (in the 0.17–50 Gy s−1 range) are evaluated using four sets of ten different probes: three sets using preirradiated samples at 80 kGy, 280 kGy, 1 MGy, respectively, and one set with pristine samples. The RIL kinetics during ≈60 h long preirradiations at constant dose rate are also studied, showing a non‐negligible bright burn effect. The main outcome is that the preirradiation improves the fiber dosimetry properties since it: 1) enhances fiber radiation detection sensitivity, 2) improves the linearity of the RIL dose rate dependence, and 3) suppresses the observed afterglow postirradiation effect. However, after preirradiation, larger dispersion between the different probes is noted, from 4% (non‐irradiated samples) to 10% for the 1 MGy preirradiated samples. The possible physical explanations are discussed on the basis of the preirradiation filling deep traps that, competing with the RIL centers for the trapping of electrons released by ionization, influence the RIL efficiency.

24. Pulsed X‐Ray Radiation Response of Ultralow Loss Pure‐Silica‐Core Optical Fibers.

Abstract

The transient radiation response from the visible to the infrared (IR) domains (400–2200 nm) of an ultralow loss pure‐silica‐core and fluorine‐doped single‐mode optical fiber (ULL‐SMF) exposed to a short (tens of ns) 1 MeV X‐ray pulse is investigated. Online (hundredths of millisecond time resolution) radiation‐induced attenuation (RIA) spectra measurements are performed at both room and liquid nitrogen temperatures (RT and LNT). The main goals are to assess the vulnerability of this class of fibers as well as to characterize the metastable defects recovering just after the shot and responsible for the RIA decay kinetics. Their identification relies on a Gaussian spectral decomposition exploiting the optical absorption bands characteristics of point defects already known in literature. By comparing the ULL‐SMF behaviors at the two temperatures, the RIA unstable contributions are highlighted from the visible to IR domains, in particular the ones that are bleached in a timescale faster than the time resolution of a few milliseconds at RT. The origin of the induced losses is discussed revealing the fundamental role of the self‐trapped holes as intrinsic metastable defects in the response of this class of pure‐silica‐core OF.

25. Photobleaching Effect on the Radiation‐Induced Attenuation of an Ultralow Loss Optical Fiber at Telecommunication Wavelengths.

Abstract

An unexpected high sensitivity to radiation has recently been discovered in a new generation of ultralow loss pure‐silica core optical fiber, the Corning Vascade EX1000. It is investigated how the injected power level of the probing signal at 1310 and 1550 nm affects the radiation‐induced attenuation (RIA) during and after steady‐state X‐ray exposure up to a total ionizing dose (TID) of 250 kGy (SiO2) at room temperature. The experiments confirm this fiber's high sensitivity to radiations, mainly due to the generation of metastable defects absorbing in the infrared domain. RIA kinetics are characterized by a non‐monotonic behavior, reaching a maximum of the radiation‐induced losses at 3.3 kGy (SiO2). Through successive radiation tests, the RIA dependence on the signal power level at the dose corresponding to the maximum of the RIA is studied, finding out that, for the two investigated wavelengths, the RIA follows a power law dependence in the 100 nW–1 mW injected power range, whose exponent seems independent on the dose rate (between 1 and 6 Gy s−1). The results highlight a clear photobleaching phenomenon, with the RIA associated to these metastable defects strongly reduced at higher injected powers of mW levels. [ABSTRACT FROM AUTHOR]
