A 2-D large area imaging system based on scintillating fibers

In this paper we describe a new detection system for the tracking and measurement of the residual range, designed and developed with the aim of achieving real-time imaging and large detection areas with high space and time resolutions. The tracker has been designed and tested as a prototype, with a large 20 x 20 cm2 area, consisting of two ribbons of scintillating fibers positioned in the classic bi-dimensional scheme. The prototype uses Saint Gobain, 500 μm multi-cladding BCF-12 scintillating fibers with square section. The track position information is extracted in an innovative way, using a reduced number of read-out channels.
