The optical-fiber-based dosimeter of the LUMINA project was deployed in August 2021 in the International Space Station in the framework of the Alpha mission. The sensing elements of the dosimeter are P-doped optical fibers, which were proven to be excellent candidates for dosimetry applications. The twofold objective of this paper is to provide a theoretical model for the radiation response of the dosimeter and to report on the experimental work carried out at CERN for the qualification and calibration of the engineering model of the LUMINA dosimeter. Combining the theoretical response and experimental data, the calibration curve of the flight model is obtained. Finally, this study broadens the investigation of the room temperature radiation response of P-doped optical fibers in a range of dose rates 104 times lower than previously reported, from 21µGy(SiO2)/h to 145mGy(SiO2)/h.

“…In the framework of the fusion by inertial confinement, dose rates exceeding MGy s −1 are encountered during short irradiation pulses associated with an ignition shot. [ 3 ] Among the possible technologies to overcome these new challenges, silica‐based optical fibers are promising candidates. [ 4 ] They can satisfy these requirements in terms of spatial resolution, thanks to their small size and volume, and can provide in situ measurements of the particle flux by following the radiation‐induced changes on their optical properties.…”

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.
