SHM in CMS Underground Detector at CERN using FBG Sensors

Abstract

The results of structural and thermal monitoring of the Compact Muon Solenoid (CMS) experiment in the underground site at CERN will be reported. The measurements are carried out by means of Fiber Bragg Grating sensor arrays installed on the CMS detector, from the inner to the outer regions. This fiber optic monitoring system represents the ideal solution to secure a reliable and accurate sensing system to be used 24/7 in the harsh environment at CERN
