Abstract

We have monitored on-line the spectral characteristics of two lines of five multiplexed Fiber Bragg Gratings under high temperature and high neutron fluence (up to 670°C and 3×1019 nfast/cm2>1Mev). The gratings have been written using a femtosecond laser and the point-by-point technique onto pure silica core (PSC) single-mode fibers. This paper details the evolution of the Bragg wavelength shifts (BWS) during the irradiation conducted at the MIT Nuclear Research Reactor.
