This paper presents the development of a CO2 laser-based heating system to simulate fast thermal phenomena on high temperature resistant FBGs dedicated to high temperature profiles monitoring within components exposed to hot plasma inside Tokamak. We have demonstrated the reliability of two optical fiber based sensing techniques to control spatial and temporal annealing measurement during high and...
The control of temperature during operation of zero power research reactors participates to the overall control of experimentation conditions and reveals itself of a major importance when measuring neutronic parameters such as multiplication factors. Within the framework of the refurbishment of the MASURCA facility, the development of a new temperature measurement system based on the optical fiber...
The control of temperature during operation of zero power research reactors participates to the overall control of experimentation conditions and reveals itself of a major importance more especially when measuring small multiplication factor variations. Within the framework of the refurbishment of the MASURCA facility, the development of a new temperature measurement system based on the optical fiber...
In this study, we have developed a FDML laser characterized by a scanning frequency up to 100 kHz over a wide spectral range of several tens of nm at 1.55 µm. Traditionally, high speed FBG analyzers able to demultiplex arrays of Fiber Bragg Gratings do not process the data continuously. To overcome this limitation, our FDML laser has been interfaced with a continuous data acquisition system based...
