A novel application of Fiber Bragg Grating (FBG) sensors in MPGD [PDF]

EPJ Web of Conferences, 2018
We present a novel application of Fiber Bragg Grating (FBG) sensors in the construction and characterisation of Micro Pattern Gaseous Detector (MPGD), with particular attention to the realisation of the largest triple (Gas electron Multiplier) GEM chambers so far operated, the GE1/1 chambers of the CMS experiment at LHC.
