Influence of the Fiber Coating Type on the Strain Response of Proton-Irradiated Fiber Bragg Gratings. IEEE Transactions on Nuclear Science, 59 (4), 937-942. https://doi.org/10.1109/TNS.2012.2206049.1558-15780018-9499https://hdl.handle.net/11441/167642We report on the effect of the fiber coating on the radiation sensitivity of Fiber Bragg Gratings (FBG). For the first time this type of study has been carried out using a 13.5 MeV proton beam up to a fluence of 3.3×1015 protons/cm2 (total absorbed dose of 15 MGy). We observed a clear dependence of the radiation sensitivity on the coating, in particular, we have investigated the irradiation induced changes on the strain sensitivity; FBG strain coefficient remains stable for all the fiber within a 5%. This result demonstrates the suitability of FBGs as structural health and deformation monitors in the very hostile environment of the new generation of high-intensity particle physics proton colliders.application/pdf6 p.engDraw tower gratingsfiber Bragg gratingsproton radiation effectstype II gratingsinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1109/TNS.2012.2206049
