(29 April 2021 – iXblue) In partnership with CNES (the French Area Company), the Hubert Curien laboratory and CERN, iXblue has developed a fiber-optic dosimeter that might be examined for the primary time on board the Worldwide Area Station (ISS).
This system has been designed to measure the radiation dose publicity within the station. It is a main problem to make sure astronauts and gear’s safety in opposition to ionizing radiation in area.
Referred to as LUMINA, this mission was developed beneath the CNES management as a part of the Alpha mission, performed by ESA. The dosimeter, incorporating two fiber-optic coils a number of kilometers lengthy, might be put in operation by French astronaut Thomas Pesquet on board the ISS. “iXblue fibers have been used for greater than 2 many years in our fiber-optic gyroscopes in satellites, and we observed that these fibers darken beneath the impact of radiation, therefore the concept of utilizing the properties of those radiosensitive fibers to measure the extent of ionizing radiation contained in the area station,” explains Thierry Robin, R&D Director of iXblue’s fiber division.

This technological demonstrator, based mostly on radiosensitive fibers particularly designed for the mission and manufactured at iXblue’s web site in Lannion Britanny, was built-in by iXblue’s area groups in Saint-Germain-en Laye. It ought to allow knowledge assortment for a number of years, which might be usually despatched again to Earth for evaluation. Certainly, the fiber darkening decreases the output gentle sign and it’s due to this fact attainable to correlate the optical loss with the radiation dose obtained, even at very low ranges. This dosimeter may due to this fact be very helpful for measuring the publicity of astronauts on the ISS, but additionally for future long-distance area missions to Mars to alert astronauts within the occasion of a photo voltaic storm and thus to guard them.
“The collection of this experiment by CNES for the Alpha mission is a superb recognition of the work accomplished for a few years with our companions on fibers in harsh environments. We’re extraordinarily proud to be a part of this mission and sit up for receiving the primary outcomes,” concludes Thierry Robin.
