SiO2-based scintillating-fibres for X-ray detection

SiO2-based scintillating-fibres for X-ray detection
Scintillating fibres can be utilized as sensors in many fields such as medical diagnosis, industrial monitoring and other scientific areas. The main advantages of optical-fibre radiation-sensors are the remote sensing and the position-sensitive radiation detection. At present, plastic scintillating fibres present limitation for what concerns both luminescence efficiency and durability (radiation hardness). In this work, new rare-earth-doped high-grade silica glasses are synthesized by a modified sol-gel method. These glasses have an efficiency comparable with the state-of-the-art BGO-sensors, high radiation hardness and high compatibility with the silica-based photonic technology. Powder-in-tube and rod-in-tube techniques are used to fabricate low-loss optical fibres with 135, 220, and 660 microns diameter. Device prototypes are obtained by fusion-splicing these fibres to commercial high NA optical fibres.

Abstract

Scintillating fibres can be utilized as sensors in many fields such as medical diagnosis, industrial monitoring and other scientific areas. The main advantages of optical-fibre radiation-sensors are the remote sensing and the position-sensitive radiation detection. At present, plastic scintillating fibres present limitation for what concerns both luminescence efficiency and durability (radiation hardness). In this work, new rare-earth-doped high-grade silica glasses are synthesized by a modified sol-gel method. These glasses have an efficiency comparable with the state-of-the-art BGO-sensors, high radiation hardness and high compatibility with the silica-based photonic technology. Powder-in-tube and rod-in-tube techniques are used to fabricate low-loss optical fibres with 135, 220, and 660 microns diameter. Device prototypes are obtained by fusion-splicing these fibres to commercial high NA optical fibres.
