Fiber Bragg gratings (FBGs) are point optical fiber sensors that allow the monitoring of a
diversity of environmental parameters, eg, temperature or strain. Several research groups …

This paper presents the novel results on fiber Bragg grating temperature sensor deployment
in high radiation and hazardous chemical environment of nuclear fuel recycle facility. The …

In-core temperature measurement is a critical issue for the safe operation of nuclear
reactors. Classical thermocouples require shielded connections and are known to drift under …

We have measured for the first time the shift of the Bragg wavelength and other parameters
of fibre Bragg gratings (FBGs) exposed to γ-radiation up to a dose of 100 kGy at different …

The radiation-induced Bragg wavelength shift (BWS) was measured with type I gratings
made of 12 fibers with very different composition, ie of fibers with an extremely different …

We report on the effect of MGy dose level/spl gamma/-irradiation on the parameters of fibre
Bragg gratings intended for sensing applications. The/spl gamma/-radiation sensitivities of …

Fiber Bragg gratings with a radiation-induced wavelength shift of<; 5 pm up to gamma doses
of 1 MGy were written with a femtosecond IR laser into Ge-free radiation hard optical fibers …

The radiation sensitivity of chiral long period gratings was investigated for the first time. After
a Co-60 gamma dose of 100 kGy they show radiation-induced changes of their transmission …

We have experimentally studied the effect of mixed gamma–neutron nuclear reactor
radiation on the effective refractive index of Bragg gratings fabricated in Ge-doped …

The difficulties encountered in the implementation of a temperature or strain sensor based
on fiber Bragg grating (FBG) in a harsh radiative environment are introduced. We present …
