Abstract
In this study, a novel monitoring system based on fiber optic technology is investigated. It is based on a full analog electronic circuitry and full passive optical devices, allowing to increase its robustness and reliability, without losing in terms of measurement accuracy. Due to these peculiarities, the conceived system satisfies the constrains imposed by the detector safety systems, a dedicated section in charge to control and handle anything is related to the equipment protection of experimental apparatus like the Large Hadron Collider (LHC) experiment at CERN. Experimental tests of the proposed system have been conducted in laboratory environment and the results, in terms of temperature variation, are shown. Two Fiber Bragg Grating sensors under test are employed, monitoring a deviation of 20°C with 1°C step, simulating a possible scenario in which the system will be employed in the next months. © 2022 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
