A superfiber for position sensitive detectors

Scintillating fibers are being used more and more in science and medicine to provide precise coordinate measurement systems for elementary particles and X-ray detection. However, low light collection efficiency (3–4% per direction typically) is still the most limiting factor. In this paper we present results of Monte Carlo calculations to illustrate some peculiarities of light collection in round fibers. According to our analyses, by certain modifications light collection in round scintillating and waveshifting fibers could be increased to about 20% per direction.
