“…Later, other researchers continued these efforts and subsequently developed several other scintillating fiber detectors for measuring neutrons in the same cylindrical form factor. [3][4][5][6][7][8] Overtime detector developers eventually began to use boronor lithium-based fibers in some cases to increase the thermal neutron sensitivity of their instruments.…”

-One-dimensional fiber-bundle arrays may prove useful in a number of radiation sensing applications where radiation detection over large areas is needed. Tests have been performed to evaluate the light generation and transmission characteristics of 15-meter long, 10-fiber bundles of BCF-10, BCF-12, and BCF-20 scintillating fibers (Saint Gobain) exposed to collimated gamma-ray sources. The test set-up used one R9800 (Hamamatsu) photomultiplier tube (PMT) at each end, with a high-speed waveform digitizer to collect data. Time constraints were imposed on the waveform data to perform timeof-flight analysis of the events in the fiber bundles, eliminating spurious noise pulses in the high gain PMTs and also allowing 1-dimensional localization of interactions along the lengths of the fiber bundles. This paper will present the results of these measurements including the attenuation coefficients of the three fiber types and the timing resolution (position uncertainty) possible for each fiber bundle when using the R9800 PMTs.
