In the field of accelerator physics, it is crucial to account for heating caused by the passage of high-intensity beams into accelerator components. This phenomenon is known as radio frequency (RF) beam-induced heating (BIH) and requires, other than an accurate design stage, to constantly monitor temperature-related parameters during the accelerator operations.

Method for the interrogation of FBG thermo-hygrometer through full analog circuit
/ Marrazzo, Vincenzo Romano (CERN ; Naples U.) ; Fienga, Francesco (CERN ; Naples U.) ; Zenga, Alfredo (CERN ; Naples U.) ; Riccio, Michele (Naples U.) ; Buontempo, Salvatore (CERN ; INFN, Italy) ; Irace, Andrea (Naples U.) ; Breglio, Giovanni (CERN ; Naples U.)
The proposed work has the aim to investigate a full analog electrical circuitry to convert the wavelength-encoded signal coming from a pair of Fiber Bragg Grating (FBG) sensors into a single monotonic electrical signal. The latter can be used either to be read from a PLC system (or directly by a switch) if a 4-20 mA signal is needed (e.g. [...]

Innovative safety monitoring system based on fiber optic sensors technology compatible with 4-20mA standard
/ Marrazzo, Vincenzo Romano (Naples U. ; INFN, Naples) ; Fienga, Francesco (Naples U. ; INFN, Naples ; CERN) ; Laezza, Dario (Naples U. ; INFN, Naples) ; Riccio, Michele (Naples U.) ; Irace, Andrea (Naples U.) ; Buontempo, Salvatore (INFN, Naples ; CERN) ; Breglio, Giovanni (Naples U. ; CERN)
In this contribution an innovative, full analog, fiber optic sensors (FOS) interrogator is designed which, being fully compatible with the 4-20 mA standard of the Programmable Logic Controller (PLC), enable the integration of the FOS technology in safety framework, such as the Detector Safety System (DSS) of the LHC Experiments. It is composed by a full analog electrical circuitry, capable to directly transduce the signal coming from the arrayed waveguide grating (AWG), into a monotonic electrical current in the range of 4-20mA.
