“…In this paper, we investigate the suitability of this ULL-PSCF to act as a radiation detector by studying its spectral RIA response under irradiation at different dose rates under two different irradiation sequences, measuring both transient (during irradiation) and permanent (after irradiation) RIA levels on both pristine samples and samples that were pre-irradiated at 1 and 2 MGy. In particular, our goal, in the framework of WP5 of the RADNEXT project [29], was to identify the most interesting wavelengths, the capability of our setup to detect a large dose rate range, the dependence of the RIA response against the dose rate and the TID.…”

This article presents a new prospect for radiation detection exploiting the high radiation sensitivity of an ultra-low 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. A pre-irradiation has been demonstrated to stabilize the response of the optical fiber and to make it even more appealing for radiation detection and monitoring. After this pre-irradiation treatment, the RIAs at 620 nm and 1310 nm in particular exhibit an ON/OFF behavior: the permanent RIA is nearly zero in-between irradiation and the transient RIA quickly increases up to 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 optical fibers.

“…This work, carried out in the framework of the RADNEXT project [16], details the mechanisms of the elastic process and extends the analysis by providing an engineering tool to evaluate the electronics sensitivity to protons at low energy. The goal is to derive a method to provide a simple way to calculate and predict the SEE cross-section.…”

This work explains that the Coulomb elastic process on the nucleus is a major source of single-event effects (SEE) for protons within the energy range of 1–10 MeV. The infinite range of Coulomb interactions implies an exceptionally high recoil probability. This research seeks to extend the investigations under which the elastic process becomes significant in the energy deposition process by providing a simplified methodology to evaluate the elastic contribution impact on the reliability of electronics. The goal is to derive a method to provide a simple way to calculate and predict the SEE cross-section. At very low energy, we observe a significant increase in the proton differential cross-section. The use of a direct Monte Carlo approach would mainly trigger low energy recoiling ions, and a very long calculation time would be necessary to observe the tail of the spectrum. In this sense, this work provides a simple methodology to calculate the SEE cross-section. The single-event upset (SEU) cross-section results demonstrate a good agreement with the experimental data in terms of shape and order of magnitude for different technological nodes.

A system-level total ionizing dose test method of satellite subsystems is discussed in the context of the radiation qualification of a satellite. System-level tests are performed with high-energy X-rays, and the irradiation results of the key subsystems, including the on-board computer, attitude- and orbit-control-system computer, and battery management system, are presented and analyzed in terms of the repeatability of the results, the observability issues, and the importance of the test conditions. Furthermore, the main benefits of the system-level total ionizing dose tests of the given subsystems are discussed, as well as the risks related to performing tests at the system level.
