Analysis of uncoated LPGs written in B-Ge doped fiber under proton irradiation for sensing applications at CERN
/ Berruti, Gaia Maria (CERN ; Sannio U.) ; Vaiano, Patrizio (Sannio U.) ; Quero, Giuseppe (Sannio U.) ; Pimentel Das Neves, Tiago Filipe (CERN ; Ecole Polytechnique, Lausanne) ; Boniello, Alessandra (Sannio U.) ; Consales, Marco (Sannio U.) ; Petagna, Paolo (CERN) ; Cusano, Andrea (Sannio U.)
In this contribution, a complete dissertation concerning the behavior of a Long Period Grating (LPG) inscribed in a B-Ge co-doped optical fiber by means of an excimer laser and exposed to proton irradiation during a recent extensive campaign performed at the European Organization for Nuclear Research (CERN) with a fluence of 4.4·10$^{15}$ p∙cm$^{−2}$ is provided. The experimental results have been thus combined for the first time to the best of our knowledge with numerical simulations in order to estimate the variations of the major parameters affecting the grating response during the ultra-high dose proton exposure.

Fiber optic sensors in the ATLAS Inner Detector
/ Scherino, L (CERN ; Sannio U.) ; Schioppa, E J (CERN ; INFN, Lecce) ; Arapova, A (Quebec U., INRS) ; Berruti, G M (Sannio U.) ; Bock, W J (Quebec U., INRS) ; Boniello, A (Sannio U.) ; Borriello, A (ENEA, Portici) ; Campopiano, S (Naples U.) ; Consales, M (Sannio U.) ; Cusano, A (Sannio U.) et al.
A prototype system of Fiber Optic Sensors (FOS) for the accurate measurement of temperature and relative humidity, has been installed inside the Inner Detector volume of the ATLAS experiment at the LHC. The goal is to evaluate the behavior of the technology against radiation effects, and possibly to assess its suitability for future collider experiments, starting from HL-LHC. [...]
