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.

Investigation of Ge/P-Doped Silica Optical Fibers for Radiation Sensing / Kandemir, K (CERN) ; Tagkoudi, E (CERN) ; Francesca, D Di (CERN) ; Ricci, D (CERN)
The distributed optical fiber radiation sensor (DOFRS) developed by CERN is a key technology for the spatially continuous and real-time monitoring of radiation dose in harsh environments. Silica-based optical fibers (OFs) doped or co-doped with phosphorous are used as sensing elements of the DOFRS systems. [...]

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.

Dosimetry Mapping of Mixed-Field Radiation Environment Through Combined Distributed Optical Fiber Sensing and FLUKA Simulation / Di Francesca, Diego (CERN) ; Infantino, Angelo (CERN) ; Li Vecchi, Gaetano (CERN ; Jean Monnet U. ; Lab.

Distributed optical fiber (OF) radiation sensing is a technique recently adopted at CERN for the monitoring of radiation dose levels in the proton synchrotron (PS) booster and in the PS. In this paper, we present the progress made on our previous work by benchmarking the rich information contained in the spatially distributed OF dose measurement with the radiation levels simulated with the FLUKA Monte Carlo code.

Solar Particle Event Detection With the LUMINA Optical Fiber Dosimeter Aboard the International Space Station / Roche, Martin (CNES, Toulouse ; Lab.

LUMINA, a fiber-based dosimeter, exploiting the radiation induced attenuation (RIA) phenomenon, has been operational inside the International Space Station (ISS) since August 2021. We discuss in this article its capability to detect the possible signatures of recent solar particle events (SPEs) through the related increase of the dose rate (DR) radiation level within the ISS.

Irradiation of Multimode Ge-doped and F-doped Optical Fibers at Cryogenic Temperatures Down to 10 K / Toccafondo, Iacopo (CERN) ; Alessi, Antonino (Fraunhofer Inst., Euskirchen) ; Blanc, Jeremy (CERN) ; Di Francesca, Diego (CERN) ; Kuhnhenn, Jochen (Fraunhofer Inst., Euskirchen) ; Ricci, Daniel (CERN) ; Weinand, Udo (Fraunhofer Inst., Euskirchen)
The combined effect of radiation and cryogenic temperatures on the response of two different multimode fibers (MMF), one conventional and one radiation resistant, has been investigated. This article presents the outcome of the measurements of the radiation induced attenuation (RIA) in those fibers at 830 nm and 1310 nm under gamma irradiation and at temperatures of 300 K, 218 K, 143 K and 10.

We investigate the X-ray (40 keV) and γ-ray (1.2 MeV) radiation responses of three different radiation sensitive Optical Fibers (OFs) up to 100 Gy(SiO$_2$). In particular, we study the Radiation Induced Attenuation (RIA) in the Near Infrared domain (NIR) for single mode OFs doped with Phosphorus (P), Aluminum (Al) and Phosphorus/Cerium (PCe) in their cores at three temperatures up to 50 °C.

Radiophotoluminescence (RPL) FD-7 glass dosimeters find applications in low to high dose radiation environments. This work presents an experimental characterization of RPL glass dosimeter, irradiated with 100 kV X-ray tubes at room temperature at doses ranging from 1.3 kGy to 0.47 MGy, much higher of their common use range.

We evaluate the temperature effect on the X-ray radiation-induced luminescence (RIL) of differently doped silica fibers obtained via the sol-gel route. Previous investigations showed that these optical materials exhibit interesting dosimetry properties, such as very good detection capabilities and linear response over a large range of dose rate.
