Radiation hardness of Ce-doped sol-gel silica fibers for high energy physics applications / Cova, Francesca ; Moretti, Federico ; Fasoli, Mauro ; Chiodini, Norberto ; Pauwels, Kristof ; Auffray, Etiennette (CERN) ; Lucchini, Marco Toliman ; Baccaro, Stefania ; Cemmi, Alessia ; Bártová, Hana et al.
The results of irradiation tests on Ce-doped sol-gel silica using x- and 𝛾-rays up to 10 kGy are reported in order to investigate the radiation hardness of this material for high-energy physics applications. Sol-gel silica fibers with Ce concentrations of 0.0125 and 0.05 mol. [...]

Optical properties and radiation hardness of Pr-doped sol-gel silica: Influence of fiber drawing process / Cova, Francesca (Milan Bicocca U.) ; Fasoli, Mauro (Milan Bicocca U.) ; Moretti, Federico (Milan Bicocca U.) ; Chiodini, Norberto (Milan Bicocca U.) ; Pauwels, Kristof (Milan Bicocca U.) ; Auffray, Etiennette (CERN) ; Toliman Lucchini, Marco (CERN) ; Bourret, Edith (LBNL, Berkeley) ; Veronese, Ivan (Milan U. ; INFN, Milan) ; d'Ippolito, Eduardo (Milan U.) et al.
The optical emission from the 5d – 4f allowed transition of Pr$^{3+}$ ions embedded in sol-gel silica is investigated for High Energy Physics applications requiring fast scintillating materials. A complete and detailed characterization of the optical, scintillation and radiation hardness properties of Pr-doped silica is carried out employing different experimental techniques including steady-state and time-resolved photo-luminescence, radio- and thermo-luminescence, scintillation and optical absorption. [...]

Dual Cherenkov and Scintillation Response to High-Energy Electrons of Rare-Earth-Doped Silica Fibers / Cova, Francesca (Insubria U., Como ; Milan Bicocca U.) ; Lucchini, Marco T (Princeton U. ; CERN) ; Pauwels, Kristof (Milan Bicocca U. ; CERN) ; Auffray, Etiennette (CERN) ; Chiodini, Norberto (Insubria U., Como ; Milan Bicocca U.) ; Fasoli, Mauro (Insubria U., Como ; Milan Bicocca U.) ; Vedda, Anna (Insubria U., Como ; Milan Bicocca U.)
The investigation of the characteristic luminescent response of Ce-doped silica fibers exposed to electrons in the 20–200-GeV energy range is reported in this work to explore the feasibility of using silica-based fibers for a simultaneous dual-readout approach. The sol-gel method allows the preparation of either doped or undoped fibers with high aspect ratio and high purity, providing good flexibility and spatial resolution for the realization of a dual-readout detector.

Optical properties and radiation hardness of Pr-doped Sol-Gel silica: influence of fiber drawing process / Fasoli, M. (University of Milano-Bicocca) ; Cova, F. (University of Milano-Bicocca) ; Moretti, F. (University of Milano-Bicocca) ; Chiodini, N. (University of Milano-Bicocca) ; Pauwels, K. (University of Milano-Bicocca) ; Auffray-Hillemanns, E. (CERN) ; Toliman Lucchini, M. (CERN) ; Bourret, E. (University of Milano) ; Veronese, I. (University of Milano, INFN Milano) ; d’Ippolito, E. (University of Milano) et al.
The optical emission from the 5d – 4f allowed transition of Pr3+ ions embedded in sol-gel silica is investigated for High Energy Physics applications requiring fast scintillating materials. A complete and detailed characterization of the optical, scintillation and radiation hardness properties of Pr-doped silica is carried out employing different experimental techniques including steady-state and time-resolved photo-luminescence, radio- and thermo-luminescence, scintillation and optical absorption. Optical absorption measurements, performed after X-ray irradiation sequences up to 1 kGy, evidence the formation of radiation-induced absorption bands related to point defects acting as color centers. Spontaneous partial recovery of the radiation-induced defects at room temperature, as well as after thermal treatments, is also disclosed. Particular attention is paid to the comparison between bulk silica, both before and after a melting process, and fibers. [...]
