The investigation of the characteristic luminescent response of Ce-doped silica bers under exposure to electrons in the 20 - 200 GeV energy range is reported in this work, in order to explore the feasibility to employ silica-based bers for a simultaneous dual-readout approach. The sol-gel method allows to prepare either doped or undoped bers with high aspect-ratio and good purity, providing good flexibility and spatial resolution for the realization of a dual-readout detector. The dual Cherenkov and scintillation light emitted by silica-based bers potentially o ers applications in highenergy physics calorimetry as well as in other di erent elds, like radiation monitoring in medicine, security, and industrial controls. The response of the bers, embedded in a tungsten-copper absorber block to obtain a Spaghetti-like geometry in a high-energy physics environment, has been investigated through a test beam campaign at the CERN Super Proton Synchrotron (SPS) facility. The discrimination of Cherenkov and scintillation light is demonstrated and discussed, along with a detailed investigation of the scintillation properties of the material: time-resolved spectroscopy, relative light output, and attenuation length are evaluated. The results presented in this study can pave the way for further material engineering and future applications. |
