Summary: | A radiation resistant single-mode optical fiber has been specifically developed for distributed sensing in harsh environments associated with MGy(SiO 2 ) dose radiation. Different types of coating have been used: acrylate, polyimide, and aluminum that allow extending the range of accessible temperatures up to 400 °C. Various characterizations were performed: radiation inducted attenuation (offline and online), fiber mechanical strength, and coating thermal degradation postirradiation. Safe operation is demonstrated for almost all coating types up to the MGy(SiO 2 ) range of cumulated dose. |
