Abstract
Tracking detectors based on scintillating-fiber technology are being developed for the Solenoidal Detector Collaboration at the Superconducting Super Collider and for the D0 collaboration at Fermilab. An important aspect of this work is the effect of the intense radiation environment existing in the detector cores on the fibers. This paper presents preliminary results of a 2 MeV x-ray irradiation of selected fibers to a dose of 140 Krad, corresponding to some ten years of detector operation. Primary emphasis was placed on studying new Kuraray multiclad scintillating and clear fibers which have superior brightness, attenuation lengths, and mechanical robustness. Two types of Bicron single-clad scintillating fibers were also investigated.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.
