Abstract

A temperature monitoring system based on fibre Bragg grating (FBG) fibre optic sensors has been developed for the gas electron multiplier (GEM) chambers of the Compact Muon Solenoid (CMS) detector. The monitoring system was tested in prototype chambers undergoing a general test of the various technological solutions adopted for their construction. The test lasted about two years and was conducted with the chambers being installed in the CMS detector and operated during regular experimental running. In this paper, we present test results that address the choice of materials and procedures for the production and installation of the FBG temperature monitoring system in the final GEM chambers.

Highlights

Gas electron multiplier (GEM) chambers will be available in the endcaps of the Compact Muon Solenoid (CMS) detector for future experimental running starting in 2021, when the CERN Large Hadron Collider is expected to provide higher luminosity beams
Along the full time history, all fibre Bragg grating (FBG) sensors provided signals clearly correlated with the current absorbed by the electronic boards, with no evidence of any correlation with the ramping/stepping of the magnetic field
The use of FBG sensors for temperature monitoring in the CMS GE1/1 detectors was successfully tested during long-term regular experimental running
