Development of new scintillating fiber detectors for high energy physics applications

Abstract

We have been developing new scintillating fiber detectors for colliding beam and fixed target applications. In this paper, we present initial results from a developmental study of high refractive index, liquid scintillators, and the incorporation of these liquids into glass capillaries. Advantages of liquid-in-capillary fiber detectors include: high efficiency and fast decay; the potential for high-resolution tracking as light emission is expected to be local to the deposited ionization in liquids containing single solutes; the potential for good radiation resistance; and replaceability.

Comparison of BCF-10, BCF-12, and BCF-20 scintillating fibers for use in a 1-dimensional linear sensor

“…[11] Using scintillation fibers in large-area radiation instrumentation found particular traction within the community of physicists developing instruments for highenergy particle accelerator facilities. [12][13][14] They have also found application in health physics and homeland security applications.…”

Innovative Low-Cost Plastic Optical Fiber Sensors for Gas Monitoring

“…In this research, low cost intrinsic sensors based on Plastic Optical Fibers (POFs) made of polymethyl-methacrylate (PMMA) [5,6] could be an interesting alternative. Plastic optical fibers can be used to develop intrinsic sensors owing to several different principles such as light attenuation change due to pollutant absorption into the core, and light losses due to fiber bending [7,8]. From this point of view, POFs have a remarkable evanescent field, which extend outside the core and can be used to develop intrinsic sensors based on the changes in the propagation losses connected to the interaction of the evanescent field with the surrounding media.…”

Modified POF Sensor for Gaseous Hydrogen Fluoride Monitoring in the Presence of Ionizing Radiations

“…Typical telecommunication [18] POFs have a large diameter in the range of 0.25 mm to 1 mm that permits to use simple and cheap plastic connectors still maintaining a good optical coupling. Optical fibers can be used to develop intrinsic sensors thanks to several different principles such as fiber grating, scintillation, light attenuation change due to pollutant absorbtion into the core, light losses due to fiber bending, etc.. [19], [20]. From this point of view, POF fibers have a remarkable evanescent field, which extend outside the core and can be used to develop intrinsic sensors based on the changes in the propagation losses connected to the interaction of the evanescent field with the surrounding media.…”
