Abstract
Considering the complex electromagnetic environments of the D shape vacuum vessel (VV) with plasma facing components (PFCs), it's necessary to build a monitoring system to obtain the strain and temperature data. This work presents a preliminary study on measuring temperature, strain and displacement of PFCs using Fiber Bragg Grating (FBG) sensors. In this experiment, a sub-system with ten FBG sensors was built to research the multi-parameters measurement in high temperature and vacuum conditions. The data of stain, temperature and deformation were acquired successfully with a high precision. In order to prove the results of the experiment, thermomechanical analyses have been carried out and the calculation results were consistent with the experimental results, which provides a base for the further work.
