Radiation resistant single-mode fiber with different coatings for sensing in high dose environments

A radiation resistant single-mode optical fiber has been specifically developed for distributed sensing in harsh environments associated with MGy(SiO2) 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 a...
